Based on the fact that most people on Suspect do run Latios, and most of those Latios run Specs, and I have at least achieved the lower requirements for voting under limited play time, my answer to you is
"No, I do not have problems with Specs Latios."
I have to agree with this. No doubt about specs latios being a top threat in a suspect metagame and in a possible OU one, but from experience, I can not say that it's unstoppable.
More or less every choiced attacker in the actual metagame can deal an impressive amount of damage if you don't have a dedicated counter (think of specs-tran, cb-tar, cb-gross and so on) and latios is no exception. Now, if it's true that he's a heavy hitter, it's even true that rarely he's cabable of sweeping entire teams with his specs'ed attacks, and every skilled player who plays the suspect knows this. And yes, this is also (or mainly) because of his pursuit weakness. If a lot of teams pack vaporeon just to handle gyarados\infernape, what's bad with packing a pursuiter to handle lati@s?
Well, this is just my thought.
Oh, and this thread is not supposed to be a RMT, so please, do not focus on specific team weaknesses.
Have a nice day.
