Can we perhaps tune down damage on locked on mage abilities?

Such as annie Q Syndra ult

They do so much damage for how simplistic they are to use. You can miss every skillshot then Press R and annihilate them for probably 50% or more hp even when behind. 500 damage on annie Q with like 2-5/0 kda

I'm sure there are plenty more examples, but how come these 2 moves in particular seem to do more damage than actual skillshot ults? You are essentially sitting at a range with plenty of cc to duel. Why do some mages just seem to be balanced around 3 shotting you with thunderlords?

Doesn't even do it as well as some other mages now. And thats HER gimmick.
