It just seems so illogical to me...
Considering most Items/Runes or anything else Cooldown Reduction related has been adjusted in some way, and Spear of Shojin is just ignored making the item users basically or quite literally without a Cooldown even if it's URF...
(AKA: 
W being permanent until the item effect ends).

True enough.
Trist mid opop2 votesrito: this might be broken. lets take some time to see if it is truly broken. rito a bit later: it was truly broken, but we will soon take away urf so there is no need to disable it
Z3Sleeper1 votesCuz the effect is extremely minimal on everyone other than Renekton.
Note that everyone's cooldowns are essentially 4 seconds or less. 20% of 4s is 0.8s. So every auto is refunding 0.8s after casting ult. It's really not game-changing imo and there are far better items to be building in URF.
