I'd love to see Legion levels of titanforging again. Not BFA, as the chance for a nice proc was so small it felt tantalizing that a titanforge theoretically *could* happen but really wouldn't..
Loot is pretty boring now and is all coming in a steady trickle from the Great Vault. No "looting the boss for a great reward". And PVP gearing becomes more attractive with every week due to the generous Conquest catchup.
I don't get why blizzard doesn't hotfix a solution for PvE as they have even acknowledged that there *is* a problem. Remember in 8.3 where they just panic-hotfixed a vendor into the corruption system? I want that kind of panic button response from blizzard now. Change something, anything, ASAP.
