An option to save different keybind profiles for characters would be a nice Quality of Life option. As it is, I don't enjoy having to set things up for different classes when I switch, or even for different sub-class if I wish to respec into another option.
#Keybind saves for different characters.

In diablo3 on each character I could reassign which skill would be used on which skill button and that would be a great QoL feature here. Especially as specialization skills are of very wide variety. Some have long cooldowns so I can easily place them on a more distant skill3 button, but some are very spammable and having them bound to easy access button is important for me.
