ROS does not need THUD so much as game currently does:
1) item evaluation will not be must-have because rares can be enchanted and they will not be so common/spammy, they will be rarer and better (worth reading tooltips).
2) DungeonKeeper will give some other statistics, that we rely on
3) If something must-have will be needed it likely will be developed in other tools
about ROS:
i think, self-found playstyle is a lot better than current "dont play & just pay" model
self-found style is the only viable option for a any game to be fun (in general)
game becoming a game and not a "workplace"
all the changes make such things, like ladders a fair things, unlike it is now.
