QWE abilities having shorter cooldowns at the cost of smaller ratios and less base damage

Might be the perfect blend that we've been looking for for healthy assassins. Their utility becomes emphasized, their damage then is no longer as front-loaded which means they must commit to targets more, and they are then most rewarded for implementing the synergy in their kit instead of having the most uncounterable initial burst.

I.E. Zed's rotation + 1 auto won't typically kill healthy targets anymore. But he'll be able to cast multiple abilities within the duration of one shadow much more easily, and his Living Shadow will have shorter of a cooldown as well. A neat thought is that his ultimate's damage will truly blow up a target when he lands multiple E's, Q's and autos before the damage happens. But only in that instance.

I.E. Fizz's rotation (trollpole included) won't typically kill healthy targets anymore. But he'll be able to dart around fights more often and stick to people (even) more easily. His W would then be the core ability in his kit for killing, since being able to stick around longer will mean he'll be able to keep applying the DoT+Grievous Wounds on a single target over a long period of time.
