Why? It’s annoying, sure, but it doesn’t make it an “autowin” against melee cleaves. If anything, just to reduce the annoyance levels, then giving it a DR is enough, but it’s not exactly something that guarantees a win every time.
Giving it a DR isn’t really much of a nerf, those hit by several would still be out of the game for quite a while and those able to dodge 'em would still be dodging them anyway.
If giving it a DR would be enough of a nerf for you, then how exactly does that remove the part that you think makes it an “autowin” against meleecleaves?
You mean getting hit by 1, being CCed for 4 sec, then hit by another and CCed for another 4 sec, and that’s when you’re hit by another and you’re CCed for another 4 sec?
