Idk.. I believe the bump mechanic to be insanely powerful, perhaps even more so than the arrows. Together with the arrows, together with a teammate, its devastating. It's like an extra attack that can attack at the same time as your main attack. That stuns the target to the ground.
Then you have bump-shoot, bump-slash with your backup 1h sword.. that you can also pick up. with speed bonus etc..
HA still a very very versatile class, and hard for any other classes to deal with. An xbower gets 1 shot off, then he can never reload. At a freely moving target.
All in all, HA is a class with extreme possibilities for creative play, and a good smart player should do well with it.
Thank god we don't have many good players playing the lamest classes.
