I think this is a very good post, which adresses a lot of painpoints in the game.
However i do not agree that food is too strong. For me it is needed to stay alive, even with a cleric.
You allready give a solution too. If they would remove food, or make it so that you can only use it out of combat, they have to remove or reduce all the aoe arrows from enemies too or this game will become too hard.
