What is would love to see changed on Cassiopeia Rework

here what I would love to see changed:

Passive: removing the 25% cooldown reduction and reduce the cooldown of the spell by itself (for the same quantity of reduction) ex: ulti cooldown (pre 250 stacks) 100 sec ---> to ulti cooldown (post 250 stacks) 75 sec .... just let this not affect the cooldown reduction but only the spell by itself) this almost let us build cooldown reduction items without limiting our build

E: since we no more need to poison the minions to last hit, I think should be good to have a cooldown refresh on E when we last hit

R: An icon over the head of our enemies when they face Cassio would be awesome
