You need to add a mage or warlock class. Also you should add a trans mog station to save styles of gear rather than the style section you have at the merchant. Add a station that can either reroll gear stats entirely or reroll the stats percentage. You should add 1-2 extra ultimates for each character so we have an option. Add a lock button and sell all button under epic rarity. Also bruenor is a great tank but as fast as bosses gets killed he seems a bit pointless. At least make it so when you put up his shield he can block the red attacks.
