rampager or zerk for grenade build
If you go spec like that I’d say zerkers. But if you go Sigil of earth and mayby 10-15 more points in firearms, to actually stack that 20 bleeds, then rampager.
You should see your average might stack size without might runes. And then calc how much the might duration would give you. 20% might duration is directly, 20% more average might.
So say for example you average 10stacks without runes. You gain 6 might with runes. That should be more stats than any other gives really.
I heard if you stack ruby orbs that’s the way to go.

Until they fix how conditions operate in PvE (as in your teammates won’t detract from your potential damage), the only class that should be considering a condition oriented build is the necromancer. Everyone else can put out more damage with berserkers by comparison. The kicker is, engineer can hit 25 bleed + permaburning + permapoison just by using grenadier, shrapnel, incendiary powder, and the 20% burn duration trait, but the moment another guardian pushes F1, that’s 20+ seconds where it’s not your burn that’s taking effect.
