Champion Thoughts

Would a Champion that loses ability power as their health goes down but the cool downs are reduced as well? That way the spells could be spammed as death is approached, but are weaker. So there would be a

• flash-like spell or Ezreal's Arcane Shift like spell for escapes and jukes
• explosive ability, with which you can also toss a minion similar to Syndra (sort of a cross between Syndra's ball toss and Zigg's bouncing bomb)
• CC, possibly stun or AoE slow.

For the Ult, I was thinking if for five seconds, if in each second for the first half every champion on the enemy team has their vision slowed, so 0.25 seconds in game is slowed down so that it takes 0.5 seconds, then it returns to real time for the second half of the second, then happens 5 times.

Would this be balanced?

PS the inspiration sort of came from Raven.
