Nah. I’d say this expansion is great for a casual player.
Say you only play for like 3 hours per week.
Well, the weekly content will take up that amount of time.
You do your covenant quests, do a low layer Torghast run, and you got yourself a legendary item, cov reward armor that stacked together is pretty great for a casual player and some fun rewards.
True casuals do group finder content and world quests. And doing what I said will make your experience fun.
It’s even alt friendly because all you ‘need’ to do is what I listed above. Spend couple hours on one toon, then do the next. The time gating eliminates any grind that would be hard to catch up.
