Before you bring Nexus Blitz back. nerf the hell out of Veigar in this mode!
I know as a squishy you're gonna take a lot of damage from Veigar, but literally being 1 shot by his W because he does 2000AP dmg, it is completely unbalanced. Not to mention, even as a tank with full MR, 3 Veigar Q's and you're still de ad. He should either not be able to get stacks of Minions/monsters or he should not be able to get stacks off champions in this mode. Something needs to go.
