For it to do 1700 damage, Veigar needs over 1175 AP if you had 1600/2200 health, without counting MR or MPen. Even with Void Staff, MR will significantly reduce damage, meaning he needs well over probably 1300-1400 AP.
You are either making it up intentionally, lying because you honestly forgot, or the game went on ridiculously, absurdly long.
Assuming you had around 75 MR, his ultimate did around 3000 damage prior to MR. Meaning he needs over 2400 AP.
Equation to calculate AP needed for 1700 true damage:
(((1700/(((1-(72/99)) x 1.5)+1))-325))/75 x 100
1700 damage.
(1-(72/99)) x 1.5 calculates the increase in damage.
+1 makes it (100+X)% of the original.
1700 divided by above gets damage prior to missing health bonus.
325 is base damage at max rank.
75% AP scaling, thus /75x100.
Equation to calculate MR reduction multiplier of magic damage if you have more than 0 MR:
100/(100+MR)
So 1700/above equation gets damage prior to MR reduction. Plug that back into first equation to find actual AP in the relevant fight, because his ult deals magic, not true.
So, want to retract your statement?
Either way, if you died to Veigar, it is 100% your fault.
His Q and E are dodgeable.
His E is cleanseable.
I forget if Fizz's E can leap over the cage.
If he lands his W on you without stunning you first, you are awful at this game.
If he lands his E on you and hits his W/Q, you deserve to die.
If you were low health and didn't respect his damage from his ult, you deserve to die.
If you don't get MR/other defensive items, you deserve to die.
