Yep, sucks. Remove the insta CC immunity, maybe make it a net arrow which comically traps them through block. Jk but make it an unblockable knockback stun instead of some weird mishmash of both.
I've tried to use it... even for fun.. and it's not even really a fun skill. To me it feels as if there's not really much utility. Maybe I'm just not good at using it but I wish it were a different skill. Not looking for an OP skill, just a fun one or a useful one.
I like using it to avoid attacks in PVP. For example, if I see a player's heavy attack or wrecking blow winding up, I can hit it and bounce out of the attack range. Or if I get hit by Dawnbreaker or Meteor, I can hit it and pop out of the AOE. Or bounce myself away from an EotS.
