I think the spell ui needs changing. Having not played 5e I actually like the changes of how you memorize and use spells but the UI does a poor job IMO. maybe group the spells by level would be a good start. I don't know if they will do that because the UI is just a MMO setup. no distinction between spells, abilities use items, and all that. I'm liking a lot about the game but the UI is bad for anything other than a multiplayer, MMo like game.
