One thing though...citing WoW...they've bumped up old content a number of times: Ony being redone from vanilla, Scholo and I think Strat were redone also from vanilla, all of outland was reworked for this latest expansion, transmog made grinding old gear just for its look into a thing for people - and let's not forget timewalking weekends Old content is a HUGE resource pool, that in most cases people are already fond of and probably missing. Bringing it back, even if it's ...later... is in most cases a damn good idea
