The build might be pretty good at 33, but damn man that's going to take a while to actually flesh that build out to be good. Also, I'd only do HA if you have MW bows and arrows already.

If you're commited to levleing up and staying at a high level, it would be a damn good HA build.
If you aren't, do a normal HA build like: 15-24, 18-18, 21-18, (or even 27/12, my personal favorite level 30 Ha, but who am i!? Go 15/24 like every other ha ^_^)
