Compare Heroic, which is done day one, with BC raids, not mythic. Mythic is way harder than any BC boss is.
Sockets/Conduits: no, everyone who farms them and isn't competing for world #1 is just taking it on themself. Not mandatory.
Anima: no, has absolutely no character power behind it. Not mandatory.
Legendaries: 2x30 min per week, for 4 weeks. Mandatory, but not more than 1 hour a week investment.
and what else you got?
