I encountered an issue with a confusing decision you can make in the game. When playing as a barbarian and getting to choose feats you have the option to pick heavy armor proficiency. Unbeknownst to me and my friend who both play barbarian you can't use rage with heavy armor. Seeing as we realised that too late after tons of progression and work we are now stuck with a feat that has no use seeing as we don't find it worth to spend all the gold and work through the grind to get back to a decent position again. I'm not asking this feature to be removed, but i do suggest that there should be some form of text in the heavy armor proficiency feat that states that it will not work with rage, alternatively it's written in the expanded rage text box while in game.
