Maxie in TS

In less than 24 hours, Maxie has gone on a rabid outburst on TS. Last night it was over the delays in getting our guild hall event started. Yes, we had people that held it up. That doesn't change the fact that it's a game and few of us want to deal with the "More Dots" guy from WoW. Today, the outburst was about talking about Heart of Thorns in TS. He doesn't want "spoilers", so after the violent rant against the people in ts, he left enraged. I can't be the only one that would prefer more restraint, and Maxie takes offense against anything very easily and does not hold back when something sets him off.

Not quite sure what to say about this, it has happened before with him... and he is prone to little temper tantrums...
