Thats pretty similar to what I am running. I am also splitting a 6 man group with another friend who plays 3 as well and together we have a 1 healer set up.
I'm running a grd, wiz, illu and my friend is running a rng, tmp, and a conj. Debating on dumping a char and picking up another healer if that would make x3 and x2 a bit easier.
