Hey guys! I'm stumped. I've done the Ultima Weapon quest yesterday and I've been wondering what do I do now? Do I need to do the HM dungeons/primals in order to progress in the story or just keep on doing the main scenario quests? I want to go to Heavensward when I finish A Realm Reborn. Long post short. Are HM dungeons/primals mandatory or optional for story progression??

Thanks!
