I feel that Veigar's ultimate is a little subpar. His ultimate deals a base damage plus damage based on the enemy's maximum mana. This means that Veigar's ultimate has a limit in usefulness and it's not quite at the power level that it should be (IMO).

Against a caster character the ultimate should be far more devastating to the target. It's an ability with limited usefulness, it should be devastating. Draining mana would be a nice buff that wouldn't require a damage boost.

with high ap you can 2 shot opponents with his ult..

His Ult is fine. With high AP (which you should go for with Veigar anyways) you can two-shot most heroes with it and Black Hole.

Say its subpar when a 700AP Veigar basically one shots your 4k health Chogath..Then call it Subpar

Morgana's shield absorbs ALL the damage of Veigar's ultimate. None of it spills over. Broken, imo.

Ult is fine as is.

Break the shield first, then ult, btw.

Yeh if Veigars ult got buffed i would laugh so hard. It should make enemy Ryze and Fiddlesticks instantly die everytime its a level of Primordial Burst is taken.
