I never see the reason to be rude to anyone. I know how what to pull and how, the limits the group and I can handle, kill order etc. My problem stems from DPS who think I'm not pulling enough (WoW mentality) or going through the dungeon fast enough. Granted, I DO NOT run through mob pack after mob pack, but once the mobs die I move on cautiously. It's part of being the Tank. Lucky I have only experienced one off player during my FF XIV play time. On any pull with 3 mobs, he would run off around a corner or where others mobs are and pull them back to me. We didn't think much of it the first few times, but after like the 8th pull we decided to fix the issue. He just kept this up until my wife stopped healing and I refused to pull hate from him. The unnecessary stress this puts on the party as a whole is pointless. We never wiped, but I place that on the fact that my wife and I were able to prepare. After 4 deaths he decided to leave the group. He got replaced and we had a fantastic run.
