"Momentum slowly decays while Slow slowed"
It's decay is so slow, that it's almost pointless to decay at all, because literally every slow is more impacting on the movement speed of the champion, than the decayed momentum.
Variks the Loyal1 votesDead Man's isn't exactly an overbearing item at the moment.
I'd say just remove the decay for being pointless, or leave it... because it's pointless.
deadlychuck1 votesRiot clearly added the effect on there for a reason, probably counterplay.
If the effect is so unnoticeable, then it failed to have the intended affect on the item.
Variks the Loyal1 votesAt the same time, though, the item hasn't proven overpowered or overbearing despite the fact that the effect is present and insignificant.
I'd argue it's probably meant to be working the way it is; the movement speed might not decay that much, but the decay probably has prevented quite a few Crushing Blow slows from being applied.
deadlychuck1 votesIt still fails to do that though, because it's so insubstantial, that it tends to only drop a few stacks /100, during the duration of a slow. Though, pretty much every slow is also going to provide enough room for them to reacquire the few stacks they lost.
