What if Ahri's ult was a short-cd, single-use ult similar to Kassadin? (MINI-REWORK IDEA)

I remember on the PBE, they were thinking about having each use of her ult lower her abilities by one second. But then they thought, "Oh really? You'd have to wait a minute just to lower your other abilities by three seconds?" which does sound silly.

So I have a slight rework that would be neat.

Spirit Rush (4/3/2 second cooldown) Passive: Ahri gains one Energy Bolt per 11/9.5/8 seconds (reduced by CDR), up to a cap of 9. Active: Ahri dashes in the direction of the cursor, lowers the cooldowns of her basic abilities by 1 second, and fires up to 3 Energy Bolts (If she has that many; if not, she'll just shoot one or two, or even none) that each pursue one of her nearest visible enemies, dealing magic damage. Each enemy can only be hit by one bolt at a time.

You could also grant one free Energy Bolt when Charm hits an enemy champion. Because synergy is nice.

So, what do you guys think?
