Well, Vayne can still dominate early game really, really easy. Only struggles against Graves and Jinx. Other than that, you set.
Even trist can hold her own, not that well against Graves, again, but still does pretty freaking good.
Kog Maw is really struggling in the early game. Only seen one game head into late phase, and Kog was powerful.
And early game casters are now irrelevant. No longer viable at all. Late game casters, also unviable since games rarely take as long XD.
Seems Cait is now busted. Pretty damn useless. Before PreSeason 6 she was great early on. Now she can barely deal damage with headshots, and Graves can just laugh it off by taking the least damage for a marksmen. And tanky supps also laugh it off barely being phased.
She is now more than ever lost in with her identity. At one point she was late game carry, then early to mid, then what is she now? Still not so great any point in the match? ^_^ I get what i am supposed to do with the traps, but she is no where near as productive and viable as before (and before, she wasn't all that viable if not, just barely viable XD)
Literally, all i got to do is Spam Graves, Yasuo, Vayne, Draaaven, and Quinn and i'm set. But that's no fun =(
PreSeason 5 was full of unbalanced champs, server issues, bugs, and other mess, but i actually had more fun. More champs seemed more viable, and things seemed more fun. Now it is just not as fun.
