Honestly when Malzahar has the highest win rate, it's the best meta to be in.
I've never had a problem with the game when Malzahar has the highest win rate, this snowball clown fiesta that has no counterplay. If we were in one of THOSE metas (the one in the title) this means that pretty much everything is no better than anything else since he's so DPS and because he has the easiest counterplay in the game, people just complain too much about it. Malzahar's damage is practically all single target and DPS.
It's hard to elaborate on this because IT JUST IS, when DPS mages are meta, they can shut down Assassins in the early game so they don't snowball as easily, but when they are outplayed in the early game (which was possible) Assassins deserved to be ahead, now it just feels all derpy with nothing right now scaling well and the only thing that does scale well is stuff that never gets played in game, I'm talking to you:

tl;dr Game is too early game dependent, we need a foundation of dps champions like malz to keep everything from going out of countrol like it is right now. We already have
, it's not like there ISN'T counterplay for constant AP DPS, we also need an item like
that isn't
do you realize how ridiculous it is building
on a
?
