I agree with him being ruined now. Low rank myself, but anyway... I can live with the lower ap ratios (even if it seems wierd to nerf his power since DFG is gone), skillshot Q, but not with the delayed stun. I have more use of it as an escape tool to zone enemies from chasing, now. And yeah, W is just for farm and teamfights, not gonna hit much else. Found that the only hope I have is to pray for having a high Q farm in late game, until then, oh lord...
He can stack his Q faster, cast his W more often, but I dont see those buffs as good enough to ruin his stun.
New Veigar: Squishy short range mage with no dash/gapcloser/freeflash and an easily escapable stun ability. With luck, you can blow someone up, late game.
