This is the build I've been using all week (this post made 3 days after launch) and it absolutely stomps. The MkVIII shotgun is like a mini-Kickback that you whip out to pick off snipers, trappers, or anything else that can slow your role as a front-line melee juggernaut. Use the Crusher on basically everything and never stop advancing and staggering enemies. Also, the grenades cause stagger (which is obviously key to this build) and you start with 5 of them + regen, so use them frequently on any packs of elites or monstrosities since they even stagger Burgles. I might type up a more detailed guide once I have a few hundred more missions under my belt with this build and tweak it. Enjoy!
