Need tooltip updates for ability damage, physical damage gains from items.

How does spell power effect something like a 3rd shot from vayne, or a graves auto, or a kassadin slash?

"It makes it stronger"

Well how much stronger?

"20% stronger"

Ok but what's that mean, is it additive? Multiplicative?

"[answers]"

Ok so its just up to me to do the math on the fly?

What about that whole thing Riot did where they said "Players should be able to focus on the game, they shouldn't be doing math on the fly or trying to crunch numbers or remember timers. The game should be helping them play their best, not fighting them or inhibiting them"

Why is this information hidden? Why am I making calculations on the fly? Why can't we just have 240+120 in orange text or blue text or purple or whatever like we do in league of legends?
