They are all worse choices due to Rock Smash.
That depends on how common Rock Smash is. I hardly ever see it on Absol because the three Rock/Steels are so uncommon. Fire Blast, Psycho Cut, and Sucker Punch are almost necessities to avoid being walled by Weezing/Steelix, and Sucker Punch is just so useful to have. Pursuit and Night Slash seem like much better options in the last slot then a move that hits certain uncommon Pokemon.
This is a pointless argument as can be said for just about any sweeper regardless of tier.
Really? If Skarmory's health gets lowered to the point where it dies to, say, Breloom's Focus Punch, Breloom now will sweep easily huh?
Saying if you mispredict against it once you will lose is a gross exaggeration. And your examples don't say much about Aerodactyl as I can easily repeat what you said for a number of pokemon in UU. If your Aggron got OHKOed by a Propobass before Swellow was sent out or your Claydol took a few hits before their Life Orbed Hitmonlee came out, or your Blastoise took some damage from a CB Crunch from a Sharpedo before DD Altaria was sent out. etc...
Do those Pokemon need to be countered? You're not playing right if you give Altaria free set-ups, Hitmonlee's only weapon against faster Pokemon is Mach Punch which doesn't effect Ghosts and is resisted by 4 other types. The Swellow example was a good one but that's specific and an actual strategy unlike Aerodactyl's counter losing a bit of health, allowing it to be killed by Aerodactyl, which is then quite hard to stop unless you pack a fast Scarfer. Also, Swellow can be revenge-killed by Aeordactyl itself.
I might like to add that you should probaly read up on a few of the points i'm now going to outline from Tangerines stickied thread on how to argue and compare them to your arguments and see how they fare.
Only the second quote hurts my argument.
The first paragraph states that simply listing facts then stating something is/isn't banned without conclusively explaining how those facts make it uber, is not a good argument. I'm presenting an argument, I'm not saying "Aerodactyl has stats of X and a movepool of X therefore it needs to be banned." I'm saying "Aerodactyl has stats of X and a movepool of X which means that it can 2-3HKO most of the proposed counters and outspeeds almost the entire metagame without situational and ineffective Scarfers, making it very hard to stop".
The second paragraph states that the fact that something has no complete counters does not automatically make it overpowered. This is sort of a good counter-argument, but it's Aerodactyl's lack of perfectly solid counters
combined with his speed that makes me argue that he's BL.
For the third argument,
Many arguments still seem to boil down to this weird idea that Pokemon is a series of 6 1 vs 1 matches and that every Pokemon must find a way to beat its counters
Seems to hurt
your argument.
