sure. thats math. however, you often dont want to spam out a spell when it is ready, but sometimes want to wait for the right moment to use it. while i agree that CDR is important, i often find myself using about as many spells with 25%CDR as i would with 40%. (except you are playing as spammy players like ryze ofc)
