Oh maaaan do I want a "Toggle" for how a character should carry their weapon by default. (Much like a "turn off helmet" toggle is needed)
Not only is the "on my back" thing silly. I seriously dislike that they don't use their weapons for casting spells. DnD requires a Focus or component pouch to cast spells in most cases. The fact that Gaels go to spell casting is "put staff on back, and wave my hands" is so silly.
How long has it been since WoW came out? I get they did it there, but this is a 2020 game, it's a bit silly they don't have better solutions for all this yet.
Oh, and when you have a torch, you hold it over your head, not dragging it downwards as if it was a heavy mace...
