So you go to get some nice transmog for your cloth toon. Sadly, a bunch of plate and two handers drop. So you switch to your plate toon.
Naturally, nothing but cloth drops.
Only mildy frustrating the first time, but by the tenth time it’s pretty infuriating. What I propose is that after the fifth, tenth, or even fifteenth time you loot an item you can’t equip, (it would make sense for rarer items to require more drops,) the item is added to your collection regardless of your class.
I don’t think this would disrupt transmog collection too much, and would add a nice progress bar to all the items you don’t have, given you more (minor) goals.
I’d much rather see a progress bar or number gauge telling me I’m close to unlocking an item no matter what than just have multiple runs with nothing to show for it.
