First off, Salamence cannot use Choice sets and spam moves like Specs Lati@s, because others have mentioned, it is SR weak and lacks special defensiveness.
To pull off choice sets, you need both:
a) many easy switch ins
b) Capacity to switch in multiple times (read: lack of SR weak, of course if your name is flygon, you're even better off), so if you screw up you got another shot.
Overall bulk means shit. It doesn't matter that Lati@s has less physical bulk than mence because lati@s isn't switching in on physical attackers (save maybe infernape). Salamence has a much harder time finding opportunities to switch in ON ENEMIES than lati@s.
Yes, lati@s was pursuit & U-Turn weak, but Specs Surf killed pursuit/U-turn users-- where as mence is not getting around SR by itself no matter what.
Your log didn't "prove" that Salamence is easy to beat or as manageable as the rest of OU, it "proved" that neither of us used Salamence to its full potential and didn't make full use of its capabilities.
All of this arguing about "skill" really is useless. If a pokemon is OP only when in the hands of the most skilled players, it is still OP. Saying "well crappy people don't use mence that well" is pointless.
lol Oh I see, so Salamence is broken-- when used to full capacity. You mean,
"Salamence is broken when it kills all my team!"
=
"Salamence is broken when it gets every prediction right and hits all my pokemon with just the right attack!"
=
"Pokemon A kills me when it predicts like a god and executes its strategy perfectly!"
. . . no offense, but that tells me NOTHING about mence being broken. If Scarf Heatran exploded on every Blissey Switch in, Earth Powered every Tyranitar switch in, and Fire Blasted (hitting each time) everything it should Fire Blast, Scarfran would be broken.
Let's not even get into U-Turn Mixnape, or Flygon for that matter.
If it takes a lot of skill, team building and/or psychic powers to bring out the pokemon's "full potential," I am sorry-- that thing is not broken no matter what potential you think it has.
