As an LPL viewer let me telly ou exactly why FPX domianted last year:
They left top side (gimgoon) for himself 98% of the times. And gave him champs that can defend well (gp, morde). So they left toplane alone and then Doinb and Tian perma camped bot side to get LWX ahead (since he gets murdered in 2v2's). If they see that is not possible then they switch lanes topside. Everything relies around LWX getting ahead.
Now Tian must gank Khan. Khan would have lost lane vs TheShy and Khan is a resource heavy player. Problem is LWX is also a resource heavy player.
Thus they dry out the other guy when they camp top like they did today. Which made them lose, since LWX is basically invisible without an advantage.
Did you start watching LPL midway through summer split of last year?
