To be honest, HA build is a bad joke. I wear a full loomed scale armor + mail gauntlets. I remember each arrow did to me around 10% of my HP. That is a joke. Also, accuracy is nerfed to the ground. If you see players that are HA nowadays is because they love that style of game. Why?
1) They have to spend a lot of skill points to have a decent build. (HA, PD, RID)
2) They are useless while on ground (0 ATH)
3) +3 Bow and +3 arrows is a must.
4) Their equipment is expensive.
There are good HA players around, like tuonela and others, but that don't mean is a good build. We all know crpg players that can own us with a stick and it don't mean the stick is a good weapon.
