SK / Warden ( or Fury) / Wizard / Illy / Troub / Conjy.

I was able to do a lot with this build, was stress free and fun.

Like others have said - melee is a chore. I tried Beastlords and while fun the melee just isn't as efficient, ranged is king for multiboxing this type of game. The only players I saw pull off melee were using third party tools to automate, technically it felt like they were botting and I wasn't going down that path.
