Berserk Isn't Working With HB For Me

My berserk is currently at 13, which means I should be getting my attack boost when my HP falls to 23% or lower. I noticed a problem though, it doesn't seem to be working with my hyper body.

My HP w/o HB is 13,809
23% of that is 3176 HP

My HP With HB is 22,0940
and 23% of that is 5081 HP

The problem is, even with HB active, berserk doesn't start up until I fall to 3176 HP or lower. As you can see, that is quite an issue.
I'm not sure if any other DrK on this server is having the same issue, but I would like to see this fixed as soon as possible regardless.

Thank you very much

 

The animation is quite glitchy and late. try attacking a mob to see if it works.

 

Oh ok, I'll give it a try
That's not a good thing to have mess up, it's kinda important to know when you're in the range without having to look that closely at my HP lol

 

Yep, the damage part works, but no flashy flashy
