I had the same question in mind.
If not, i think i could manage to do it. Depend if anyone would need it though.
I was thinking of these features :
- Would be based on actual fighting mechanics with a few changes :
- Stop trying to loot stuff on the ground that doesnt belong to you
- Implement some kind of pause between launching a new rifts
- Try to stack Magic item buff by staying near active people.
