1. Fire - There isn't too much Talon can do against Fire. Fire has access to quite a few Stealth Rock users. Talon cannot do much against Rotom-Heat or Heatran, which can be commonly used fire types. Only things Talon can really hurt here are Fire/Fighting types (Such as Infernape) or something at low HP. Little Priority.
2. Water - Water has access to quite a few Stealth Rock users and a variety of Physical Walls or potentials. Being a supereffective type to Talon, it does not suffer to it. Some Priority (As in Aqua Jet which can easily take it out depending on the pokes attack).
3. Grass - Grass is seriously countered by Talon, on either Flying or Fighting. Grass normally is a bad defensive type, however it suffers badly to a Fire/Flying type with priority flying moves. There are some pokes that could potentially attack it with a sash, but without one, Talon dominates most pokes. However, think if Gale Wings was banned. Some pokes (Like a scarfed Ludicolo in Rain with Swift Swim) could be able to kill it, so grass could see a little more usage. Grass would like the ban of Gale Wings.
4. Electric - Talon does not harm due to being weak to electric, as well as electric having fast pokemon such as Jolteon, Mega-Manectric, and Thundurus. Electric has limited Stealth Rock users however, but in the case of being fast, that is not an issue.
5. Fighting - Talon easily deals with pokes in a Fighting Mono. Pokes like Terrakion and Cobalion barely take one hit, but if someone was smart, they would switch out into something part Ground or Rock or whatever stalls out these pokes. Fighting has access to a lot of priority but has limited Stealth Rocks (In the form of Cobalion, which, against Fire, doesnt get its chance to set those). Fighting would like the ban of Gale Wings
6. Bug - Bug is a mixed situation. There is some priority and a couple ways of unleashing Stealth Rocks, but does not like either of Talons types. A few good pokes suffer from Fire Weakness (4X) while others suffer Flying Weakness. Armaldo does not stand up against Skarm too well. One of the major things about Bug Types tho, are the Speed Boost Yanmegas and Scolipedes. Both of these have potential to take down Flying and Fire monos, but can easily be checked and/or countered.
7. Dragon - Limited Stealth Rocks, limited priority, access to Fast Scarfers like Latios, Noivern, Salamence which can easily KO Talon. There are also limited Physical walls. I dont think there would be much change to Dragon
Flying - Flying has Stealth Rocks, only a little priority in the form of Extreme Speed Dragonite or Quick Attack Staraptor, but has quite a few walls able to withstand Talonflame as well as fast attackers. I dont think there would be as much change in Flying.
8. Ground - Ground has nothing to worry about against Talon.Packed with Walls, fast pokes, and Stealth Rocks, there is plenty of things that can beat Talon. There is only a few priority though, but overall, ground doesnt change too much.
9. Rock - Rock is very similar to ground, only even better against Talonflame. STAB 4X Effective moves kill without question unless by an extremely weak attack. Access to plenty of SR, extremely fast pokemon (or set ups like Omastar, but Omastar easily dies to Priority if at low HP), as well as Aqua Jet Kabutops. There are good walls against Talon so overall, it doesnt worry about Talon.
10. Fairy - Fairy has access to pokemon like Klefki who could set up screens to cripple Talon, as well as access to Azumarill for a Belly Drum Aqua Jet combo or just the Aqua Jet or Waterfall itself. It has few stealth rocks and few walls. There shouldnt be too much change for Fairy.
11. Steel - Steel, being a type that is weak to fire, normally looks like it would suffer, however, access to Heatran, Aegislash, and Lucario can easily deal with it by walling or outspeeding it with Priority (Extreme Speed Lucario). Steel has access to Stealth Rocks easily enough as well as priority for some pokes. Overall, it helps Steel handle Fire and
Flying better.
12. Normal - An overall versatile type. Normal doesn't suffer too many movepool restrictions, and has access to plenty of walls and Stealth Rock users. There are some fast pokes, there are also pokes like Ditto which can easily take the opponents team for the normal team user's purpose. Ditto has the option to transform into a Talonflame and take any boosts it currently has while being able to take out a lot of pokes thanks to Gale Wings. If we were to remove Gale Wings, very little would change.
13. Poison - As a whole, Poison isn't the best against Fire. Poison does have Stealth Rocks, but it is not one of the best types. It has limited walls (Although they are pretty potent) as well as limited pokes that are really fast. Crobat gets 2HKOed by Talon, and has little it can do to it. Scarfed Nidoking isnt a bad option for speed, but it gets 2HKOed by Banded Talon. One actual check to Talon would be Max DEF Weezing, as it only gets 3HKOed after Black Sludge and also has Thunderbolt. I think the removal of Gale Wings though, would help Poison shine a little more because Gale Wings easily picks off low HP things (As previously mentioned)
14. Ghost - Ghost is a type of mixed opinions for what i think would change. Ghost has access to Stealth Rocks with the handy ability of its type being immune to Rapid Spin (Though its not immune to Defog). Ghost has fast pokemon like Scarfed Gengar and Froslass, which could potentially deal with Talon MINUS the Gale Wings. True there are walls like Eviolite Dusclops, but being a Fire Type, Talon is immune to Will-o-Wisp. Toxic would be needed, and even then, Swords Dance or Bulk Up Talon can occur. Overall, ghost would benefit a little in my opinion.
15. Dark - Dark I think doesn't suffer from Talon. It has Tyranitar for rocks, Greninja for a fast Water attacker, Mandibuzz for an excellent Physical wall. Dark has priority Sucker Punch to deal with Talon to. I think overall, Talon really doesn't touch Dark too badly, so Gale Wings shouldn't change Dark too much.
16. Psychic - Psychic is an interesting type. It has plenty of options for Stealth Rocks, plenty of fast pokes to combat Talons speed, and quite a few physical walls. The only thing that I could really say that gets hurt by Talon are those Psychic Types who are unable to take a hit, such as Alakazam. Medicham doesn't like Talon too well either. I think Psychic would gain a little more usage without Talonflames Gale Wings about.
17. Ice - Ice started out as a bad type this generation. With the buffs to things like Fire and Steel, Ice has seen little to no use. It has few "viable" options to use against Talon like Weavile (Even though it can only 3HKO with Life Orb Ice Shard and is outsped by Talon) as well as Froslass (If you can try and pull a Sash D-Bond or Tbolt). There are relatively few Stealth Rock pokes and even fewer walls. In my opinion, the ban of Gale Wings wouldnt make too much of a different to ice, but it would do a little...
18. Flying - Flying is an open type. It doesnt need Talon, but uses one. It has access to plenty of Stealth Rocks, fast pokes that can easily 1HKO Talon (Without Gale Wings cuz Priority kills some pokes off easily), and has some priority. Flying can easily handle Talon So I doubt most changes would occur.
One thing to note is that I put this in a matter of perspective by what gets hurt by Talon. A type like Steel would be better against Fire or Flying by dropping Talon, but I only talked about what outright gets boosted by Gale Wings banning. Any small "This type can handle Fire and Flying" comments aren't mentioned because its an implied thing.
