if you devs are considering keeping parts of the rift-system:
how about customizable map cycles? i guess this becomes editor-territory. have us be able to choose from all the environments and maybe different light depending on time of day if you´re maybe bringing that onboard.
same with preferred monsters maybe?
I wouldnt mind having a “Trial” system where you can test your build against specific enemies. As long as it comes with zero rewards.
Any dungeons that offers rewards should be randomized. Anything else would be completely imbalanced imo.
A customized battle map to test yourself or just to murder the things you enjoy the most would be fine, provided it doesn’t earn anything - not even money or EXP - since its all personal and possibly sharing with others to see what they can do.
Otherwise, every random map should include every possible option - all monsters included, all maps available, all “time” and effects, even those which may not normally be possible… like, say, ice storms in a map filled with lava.
