I made a "transmog farm" team consisting of a Warrior, Druid, Hunter, Mage and Warlock, so I could cover all weapon and armor types, and other than class-specific armor tokens, I can run old content and collect all the transmogs.

Worst part is having to trade all the loot around after the runs, before the appearance is learned. I then use a repair mount that auto vendors all soulbound gear below a given item level, set in EMA. I wish there would be a way to auto-trade all tradeable BoP raid loot.

It would be super cool if you could change loot options in a party, of say all guild members, or of all chars on a given battlenet, but that would never happen.
