Even in guild runs this would help. Yesterday I was was in group with 2 druids that bid on all the cloth items. I’m sure there was some after run trading around for the gear. It was mostly a guild run but no one was paying attention.
Class specific gear like honor gear would change everything. Priests, Warlocks & Mages ONLY can get cloth. Druids & Rouges ONLY can pick up leather.
AND once an item is picked up at roll, it can’t be traded. No more loot master holding gear until end of raid.
