what if the armor shred on garens spin would be replaced with this?
enemy champions hit with 4 spins lose 25% of their armor for 6 seconds
with
when enemy champions are hit by 4 spins, judgements cooldown is reduced by 1/2/3/4/5 seconds (scaling with rank)
i included a rank scaling to actually put some value on putting ranks into the ability.
alternatively it could just be a flat 2 or 3 seconds, to make those windows between spins just very short mid to lategame at 40% cdr, while you stay in the fight.
the only thing that would need to be looked at would be to disable urf mode spin stacking, when the spin gets cancelled early and effectively goes into negative cooldown.
