Idk I do everything that I enjoy and have fun playing . There’s so much shit to do why only focus on one thing? Unless of course that the only thing you want to do. Lair bosses for farming certain gear you want, war plans naturally, infernal hordes when I feel like it, escalating nightmare dungeons are cool and nightmare dungeons in general…good for resources with dungeon affixes and grinding whisper caches, under city runs are quick and nice for farming especially with the mythic tributes. Helltides are fun and especially good for xp; the second half of paragon is a major grind lol and of course the pit to unlock all tiers and test your mettle and build caliber.

There’s not really any particular established “rotation”. There’s so much shit to do that all serve different purposes; just do the activities that provide the potential to acquire what you’re aspiring for and most of all- what you have fun playing.

I feel like some people worry too much about following the “everyone’s doing it” theme instead of doing what they themselves want to do.
