I just started 3 boxing rift as well, I have necro/lock team up to level 16, have done 2 warfronts so far, no self heal yet so I died a few times more than I should but I still got 26 and 23 kills in them.

I have 3 inqus/justicars I started too, that seems fun.

I want to try ranged rogues as well...

So many combos.

Razer naga mouse helps out a ton.
