WitchHunter Has No Point

I was watching MinerJohn play today and he became a witchhunter and I thought that sounds cool, because of the different arrow types and whatnot. Then when he trys to change the arrow types it says he is only allowed to change to normal and can only use leather. I understand the leather if your able to change arrow type but w/o arrow types this class has no point and should be disabled like enderborn was.

And no one cares...

left click to change arrow type, need power to shoot the arrows
