Im suggesting loadout profiles for characters.
This would save all the passives, skills, idols, and items into a “profile” that can be used to quickly swap builds for a character.
For instance, if I play a bowmage marksman and I want to try a different build for that marksman like elemental arrow, or maybe I wanted to use the melee detonating arrow dagger then I can save my current bowmage to a profile while working on a new build for the dagger. That way I dont need to spend hours working on a build I already did if I want to come back to the bowmage. I can just select the bowmage profile and it puts everything back the way it was when I saved the profile.
