I feel your pain. My dps set only contains about 4 other pieces I switch out, I haven't had to branch much for that yet. My healy set sits at about 1550 + heals unbuffed in tree. I don't have much of a boomkin set yet.
I'm still rocking blue chest and pants. Waiting on those Gored Hide Leggards from Gundrak.
The chest, I'll probably get something soon, either through emblems for the tier piece or finally get some decent melee leather to drop in Naxx.
EDIT: And blue gloves. >.< WTB Leather drops in Naxx!
