Meta Knight. I know that and I don't even have the game.
I smash the stuff out of Meta Knight with Marth. And he got nerfed in brawl.
And by lag-free you mean the minimum ping is 500. Also TF2 is really balanced. I don't see why you say it's so unbalanced.
I've only had lag issues ONCE on Brawl, but that was my connection.
Assassin's Creed Brotherhood is pretty balanced.
Everyone has the same chances of killing somebody, and only the really high levels can use the Hidden Pistol.
The hidden gun was a low level weapon, and gives you a stuffty score when you use it.
Poison is something to complain about. That agony bonus is ridiculous.
