The game phase thing varies, Vsagent. It may be wrong to state that Lee Sin's damage falls of late game, because that's entirely dependant on build and not a part of his identity, but Karma being an early game powerhouse is both identity (Riot has stated so) and in practice. No matter the build, Karma has a huge lead early on.

So what I'm saying is: it's bad to mention game phase power curves that are entirely dependant on build, unless that build is obviously the correct one (yes, Twitch won't be a menace late game if he builds tank, but you're not supposed to build him tank). It's okay, however, to mention game phase power curves that are part of a champion's identity or come from mechanics in their kit and not the items they get (ex: Karma having her ult at level 1, Cassiopeia's passive making her a late game monster).
