Will discuss with the team.
tooltip dps/stats shown for each selected skills
This is planned but will take a lot of time to implement; won't be ready soon.
Able to buy back the last x items sold to NPC

Players to be able to choose which passive points to respec, but not respec the last x points invested.

Press Alt to show the Tier of the Affixes.
Good suggestion! Will discuss with the team. :)
