I wouldn’t honestly expect to see this - and I know for some of those that still play, it’s not really an issue - but for players like me that played less and less over time, I would love to see a mode that removes mystic re-roll restrictions and insanely enhances drop rate for primals - divorced from all other game modes, of course (so no overlap in storage or paragon levels or anything with anything else.) Basically, I’d love an opportunity to really live the top end power fantasy I could never get to normally. Basically, spend a weekend just seeing what I can create and what it’s like.
Again, I know there are players that have done that themselves, running full, BiS primals and such - but for me, once I cleared Grift 70, that was the last goal for me. The only next one was to push further and try to earn full BiS primals, but the amount of time I would have had to sink into that given all the layers of RNG - item has to be legendary, item has to be the one I want, item has to be primal, no more than one stat can be one I don’t want - it was something that immediately turned the game from goal-oriented to one I popped into every now and then just for fun.
Again, it probably wouldn’t give much to the game, its playerbase, and it certainly wouldn’t make Blizzard any money, but it would be fun for ME.
