Can we seriously buff Kassadin just a bit?

I would honestly like to see a base damage increase on Q,, for a basic ability that has a 9 second cooldown at all ranks, 170 base damage is pretty bad, Need I remind you Katarina's Q does 160 base damage at rank 5, it's resourceless, and has a lower cooldown than Kassadin's Q, and she is almost as mobile as Kassadin, oh and did I forget to say she's an asssassin with insane scaling? Let's not forget E which has to be stacked only does 180 base damage, oh and W a melee ability only does 140 base damage.

My proposed changes?

Q: Damage 70/100/120/160/190 + 0.7 AP

W: Damage changed to 20/50/70/130/165 + 0.7 AP

E: Damage changed to 40/90/120/160/210 + 0.8 AP

R: Unchanged

TL;DR I know my match history might look OP in some spots of the week, but I as a Kassadin semi main still think he is vastly underpowered vs a lot of team comps. Those 5 games I wrecked on Kassadin on Saturday, I have to say I don't think I was vs very smart people cause they were playing extremely sloppy, but if you play vs a decent team they will make Kassadin useless with his ult range.
