health above 70, melee above 120, weapon above 100, whatever the rest, but 3 enhanced athletics - legs. I tend not to spec into grenades on hunter for weapons with demo or mods can gain them back quickly. the double melees on some subclasses helps counter the lack of grenade. Solar, lightweight knife (kills make you radiant) tripmine (grenade kills create orbs with firepower mod) or heal grenade, blade barrage, if you run with assassin's cowl every powered melee kills grants invis and where you can have infinite throwing knife on kills, that's a fun one or Void, graviton forfeit and do the "I can be invisible forever" build, tether super or Arc, tempest strike is fun, being amplified easier or Strand, is probably the one man army between grapples and twirly birds, super is not great for boss damage though using mods like Reaper, Firepower or kinectic/ your flavor siphon or a weapon that has attrition orbs help the orbs creation. I dont spec into class, my hunter is at least 75 heatlh, 120+ melee, 120+/- super, weapon 120+/- the others I feel are meh. I do notice a diff at 70 then again at 120 then again at 150 no matter what atribute you desire.
