Because there is a character wipe with the new season, if I’m close to finishing the campaign, should I just focus on that and get all the altars, and avoid everything else? I don’t see much point leveling up and planning out my character build and obsessing over equipment if it’s all going away in a week.
I’d say yes, focus on renown and altars, as you keep that part of the progression. As for the rest, it will likely be easier in season, especially if they do something about monster density :)
