@riot What if Cassiopeia's E interacted differently with CDR?

A small idea i had in my mind

so instead of the normal way CDR is counted what if her E's cooldown was reduced by 0.01 seconds for every 1% CDR Cass has Assuming Cass has 45% CDR Cass's E would have a 0.41 second cooldown with 45% cdr with this interaction it could have a max possible difference of 0.11 seconds at lowest the cooldown would be 0.3 seconds with 45% cdr
