"Shrowd tail has been fixed" said the previous patch, well that was a lie.

Anyway, the tail hitbox need to be fix but not only that, re-designed because some weapons can't even hit the tail because it goes in the air alot of time and due to the form of the tail, i've seen alot of player including me miss their hit on the tail, especialy with combos where the slayer stay where they are and not move a little forward cough war pike cough.
