I'd also like to add a suggestion on here as well

Seeing as how many different spells/abilities each character can get, I believe that we need an option for multiple skill bars (like WoW)
I'm not in beta, but for sure this! The one thing I ask for turn based combat is when I make my move I want it quick. Not open the inventory/spellbook often and do things from there. With the advancement of UI's over the years, this to me is a huge deal with bringing turn-base combat back into the mainstream. Elegant UI.
