Yeah, sounded weird to me at first too until I realized how major the “solo” part was. No more 4 man advantages. Also, they’re limiting paragon points to 800. I’m sure that will be controversial. Probably a good idea imo. High endgame power should come from gear. Just wish they’d have better gear like D2.
