One change I am all for is druids getting a ressurection skill. I was a resto druid back then and it was a pain in the arse not being able to ressurect teammembers. He/she had to run back and they might encounter patrols so the whole party had to move back.
I believe the argument back then was: The druid can stealth through the dungeon and keep rezzing their teammembers but it seems to nonsense nowadays.
What would you change?
