Hiho.

I'm bored, so I thought I'd start a discussion on group builds.

First time playing the game I played a rogue (class of choice) and populated the rest of the group with proper npcs with their back-stories and funny quips. Second time around, just for shits and giggles, I played a ranger with another 5 created ranger toons. I found that, aside from a few specific battles, the game was way easier with 6 rangers just blowing everything away (even the final battle was way easier with the rangers, I felt).

This was like 6 months ago and I haven't really given it much thought since, but would this work with any class? Is there some class that'd make it even easier having a full group of said class? Discuss.

6 rangers works this way mostly because You have 12 party members.
Having 6 Barbarians with dual wield works as a mascrator too. But it is not funny at all. Also try this on PotD...
