As the title says, since the update today on 31/03/2015, this skill has much longer aftercast than what it had before, and aparently some other skills that have the same animation have that problem too (on other topic anout throw gunk/ feather tuff), so this si definetly a bug.
The bad part about ranger is that its a weapon skill on 10 secs cooldown which is very problematic in pvp since i could throw an auto axe and a half in that extra aftercast they added now.
Also, it looks than the animation its correct, but the axe comes out like 1/2 sec after it did before, and also it takes longer to use skills again, like an entire second total delay added.
Other skills work perfectly so its not lag, and it happens always i use winter´s bite.
I hope this gets fixed as soon as possible.
