Even if Dragalge doesn't get Adaptability (and though it looks like it doesn't, surely it ought to have a hidden ability of SOME sort?) it will be better than some of you are giving it credit for. Goodra definitely has better stats, but Dragalge's typing is much better for a defensive Pokemon and it has actual support moves with which to support its team. Unless UU ends up radically different, which I highly doubt, fighting-types are still going to be very strong and Dragalge is an excellent Heracross check, takes HJK much better than Goodra (though neither Pokemon handles Mienshao particularly well), handles Roserade much better because it has a 4x Grass Resistance and Poison resistance, can beat the admittedly uncommon Arcanine much easier because it resists Close Combat, potentially can take fairies on much more easily since it not only has a super effective STAB but also isn't weak to their moves, takes Umbreon and Sableye on much more easily since it doesn't give a shit about Foul Play (Possible 7HKO on 252 HP -ve attack Dragalge), is much less vulnerable to U-turn exploitation and can't be toxiced, which gives it great longevity. That's a pretty big list of things it can do better than Goodra, mostly because of that stellar Poison typing; Poison was already one of the best defensive types in the game - and this was exploited by Pokemon like Nidoqueen and Tentacruel to great effect - but now it gained a topical resistance and lost some of its offensive worthlessness it's only gotten better.
That's not to say Goodra won't be good, I look forward to playing with a tank set should it drop to UU - but it's really more of a tank where Dragalge is perhaps more of a defensive Pokemon (assuming, again, the whole adaptability thing is a hoax or npc bs) with more resistances to use to its advantage.
Dragalge is not making it to UU sorry. Between massive physical attackers like Mienshao, Rhyperion, Flygon, and Weavile who each hit it on a physical side this guy dont make it (not to mention each of these guys are pretty abundant). I could admit to going so far as to say this guy could be BL2 because in RU he'd easy wall things. Still these are the factors which to me hurt Dragalge's upper tier status:
-abilities are the same in different fashion and can both be accomplished through SludgeBomb or Toxic
-in comparison to Goodra (stats) it only beats it in defense and 70 vs 90 is not exactly a big difference when you only have base 65 hp
-the only current offensive set you can run is either Specs or sub/3attacks
-it is 2x weak to Ice, Ground, Psychic, and Dragon each of which is in the UU tier
If you want to compare it to Goodra then you have to recognize that:
-they can each learn the same Special attacks that could possibly be used between the two of them
-Goodra has a niche spot in Drizzle or manual rain because of Hydration
-Goodra has 1 less weakness/Dragalge is weak to Earthquake probably one of the most used attacks
-Goodra cannot be walled by Steel-types like Dragalge (Goodra gets Flamethrower and EQ [anyone 1-up to Dragalge])
I truly don't mean to assault this pokemon at all because I was very excited for it but it proved to be a slight disappointment. As I said before this guy has great promise as a wall in RU but up in UU it would just get countered by things like Empoleon, Bronzong, and Scrafty or die to a Krookodile, SubBisharp, or FLygon
