This is the best build I found so far after some tests with Bow turned out disappointing. Could push to 83k I think.
Run vMA Inferno backbar - gives 8% more damage and more damage on light attacks, easily applies Berserk enchant with blockade.
Basically, backbar you just cast Blockade every 14seconds. Rest of backbar is filled with fighters guild abilities, I don't think it even matters what's on backbar, just Blockade for weapon damage enchant.
Frontbar - cast blastbones (3 in 1). So reapply trap and archer when off CD and Siphon (still buggy) rest is Venom skull spam.
Dawnbreaker as ulti, I don't think it's worth using colossus for individual DPS anymore, at least I didn't get good result.
With Bow I was doing 79k, perhaps could do 80k, but you need Arrow Barrage to get 100% berserk, just PI gives you 50% berserk, and Barrage very stam intensive, so need to do some heavy attacks.
With this build my stam is always above 70% so no sustain problems, can even use Maarselok in Raid, since you need more negative effects, Zaan is also decent actually it will do more dmg than Velidreth, just you lose weapon damage, so overall perhaps not worth it.
I think this can work for other stam builds as well, especially those who struggle with sustain. This is DW build without DW skills ^^, RIP.
