I really think this should be considered, we have not gotten bigger bags yet we keep on getting new gearsets.
Can we please get the capability to swap tier roles at the vendor? I currently carry all of tier 1 and 2 for both DPS and tank sets and now am accumulating 2.5. I keep the tiers because of their resistances. It would save me so much space and time if I could just go trade back in my tank tier and buy back the dps role of the same set and vice-versa. The penalty would the loss of enchants and in the case of AQ scarabs and idols.
Meta is constantly chanting too so sometimes you may grab a couple of pieces from one role for a specific utility benefit and then the meta changes and you’re stuck with what you have and now need to reroll for tokens, which just deprives other people of gear.
I can’t even imagine what shamans go through with dps, tank, and healing sets. Please just let us return the piece, get our token back, and get another piece.
