I'm curious to hear your thoughts on this matter. A friend and I were discussing the playability of a monk. I know it's not a very good class but I really enjoy playing the class. Always have. I understand there are better options. I say it's my character I'll play it how I want. His argument is that other players shouldn't have to suffer because someone wants to play an un-optimized character. I assume he means in combat. So here's the question...
Lets say someone in a game you were DMing is playing a truly terribly built character that they enjoyed. Would let it be? Tell them to make a better one or version of that character? What would you do.
