This may have already been mentioned in a previous suggestion, but I think alot of the players would benefit from having a separate trait build when entering dungeons, similar to the automatic trait change when entering sPVP.
Many of us trait specifically for doing dungeon content in order to better synergize with our group members, and typically these builds aren’t as effective in world PVE content.
I don’t mind the cost of changing builds, so possibly offering an additional trait build tab players could unlock for dungeons with in-game currency would be a good alternative.
