I've been playing Vaigar on the PBE lately, (Mostly custom, so I can expand on this once I play PvP) and I feel like one of the most fun things with Veigar is gone. I really liked being able to q and r one specific champ in a team fight, and that's what Veigar was known for. I fell like the skillshot makes it hard to blow up that single champion. That's my opinion, and maybe he wasn't healthy enough before, but I'd like to see what others think. :)
I get why they changed Q to a skill shot to avoid 2 target nukes, but IMO the ult should be the skill shot while the Q should still be targeted, allowing a for a reliable damage source throughout team fights. The .75 second delay is also too long to really be useful except as a zoning tool. Nobody who is actually paying attention will ever be caught unless already CC'd. The new Veigar changes do not impress me and I feel they definitely leave a lot to be desired.
So your argument is that Veigar should be able to instantly blow up a champion with 0 counterplay using point and click abilities that require no skill. Go on
