Yes, the current system is just sad. I've been clearing T7 almost every week since 2.2 came out and never saw the healer robe. I did like 20 other runs after the the lockout has been removed, still not seeing this robe.

Dunno about you guys but every goddamn time I want a piece so badly it doesnt drop. I've looted twice when I though I would loot nothing in final coil, and I'd like to get the monk's robe and I think i'll face the same issue, like if some kind of god was watching on us...

They should just allow people to trade off their useless pieces to get the ones they want to. Considering they added another class in 2.4 it'll be even harder to get the right loot.
