Best mix of survivability and damage output
That depends alot on traits and utilities used in my opinion.
For example, If I run with an good condition removal, I go toughness because in my number crunches, it negates more damage the Hp can absorb by 3 to 8 ratio. But if I am using a build with a different focus, and have no condition removal I may go more Hp heavy.
As for damage, are you looking for condition damage or direct damage? single target or AoE?
I’m not sure if its a good balance, but my setup seems to do fine out in Orr and WvW (I don’t do sPvp). Primarily using rifle and grenades for DPS (though I swap in flamethrower and toolkit for giggles quite often).
Not quite done on my gear but when done I should have a little more armour and health than currently (i’d like even more, but give up a lot of damage for it).
Attack: 3460/3045 (rifle/kit)
Crit Chance: 41/35% (rifle/kit)
Critical Damage: 55/46% (rifle/kit)
Armour: 2092
Health: 19,112
Traits: 30/10/0/30/0
I keep elixir B and medkit 5 active as much as possible giving me permanent swiftness and fury (and 3-5 stacks of might), so 1 utilit is Elixir B, 2 is grenade kit, and the third changes on my mood – Elixir S often for the “oh crap!” usage.
Gear to get this is mostly bezerker and ruby gear, with a piece of solider armour and a valkyrie amulet (+ some emerald orbs in the armour). With a quick trait change, I can quite quickly swap to (almost) full glass cannon as well for the ‘static discharge’ build and working on karam for a full soldier set at the moment for when I want to be super tanky.
