I realised something ...
You can now very easily get 75% ult CDR .. almost urf level or 85% if lucky or 95% if extra lucky)
With ultimate hunter giving 25% (5 + 4 per stack (20)) 40% CDR standard thats 65% ult cdr
but with cloud if you get 1 thats 75% CDR or 2 clouds thats 85% and with 3 thats 95% but if you manage to get 4 thats 105%
i feel like using ultimat ehunter and getting the 40% in game and getting clouds would be very rewarding for champions with low CD ults such as Zilean and liss
I played a game just now with liss i had full CDR a cloud and 4 stacks of ultimate and at rank 3 mu ult CD was 33% if i got that final stack it would be just under 30%
this would be so strong as you can easily not be pnished so hard for having a quick 1 v 1 or skirmish before a drag which is obviously valuable atm o_O
one day i dream for that 105% CDR
