Oh my god, Iron Bull sucks. I like him as a character, but he is supposed to be the tank and he is always the first to die in battle. Whats his problem? Hell no. Goodbye.
You have to control him yourself. Or make him a sword and shield build, which sucks since that doesn't work that great with this specialization. I'll take him along on missions I know are going to be easy. Otherwise it's Cass and Blackwall for my warriors
