Actually my main concerns were,
a) Leveling in a new expansion. Too long IMHO. Blizzard is wasting resources making content people aren't enjoying. Alts didn't really come to mind.
b) RNG gear being the only form of character advancement at level cap is incredibly frustrating. Some weeks you get the motherlode. Some weeks you get nothing but repair bills for your effort. RNG is great for "bonus" stuff IMHO. But there need to be a "salaried" reward too - preferably one that doesn't clash with RNG drops *cough* VP gear *cough*. Leave the RNG gear as a bonus way to advance your character, rather than THE way.
