There are number of gears design solely for the Bounty Hunter.
But would you choose to have 6 pieces of 1 set or no?
Here're tips for all of the Bounty Hunters:
You will need 2 piece of each Set exactly. Because the BH relies on extreme DPS, slight tankiness not to get 1 shot by boss and enough recovery so you can still fight.
Power (For DPS) 85-90 power is the best
Critical rating (DPS) 85-90 Crit rate very advisable
Critical damage (DPS) 57-60% the maximum possible Crit damage
Attack speed (DPS/Recovery/Proc of passive skills) 13-14.4% max Attack speed rate you can reach via items.
2 assault gear: for the additional 5 projectile on the scatter shot (additional DPS)
2 havoc gear: plainly for the 500% weapon damage on the missile (additional DPS)
2 stalker gear: if you have 5 additional projectile you also need 15% more on piercing so the projectiles will penetrate and damage more enemies.
