Look, I understand that you’re proud of all you’ve accomplished in this game, and rightfully so. However, I think that there and positive and healthy ways that you can express that pride and there are also negative and unhealthy ways. I think posting threads on the forums and making youtube videos about how awesome you are is very much in the former category.
However, I think that being a berating and being a dick to everyone you play against is perhaps approaching the latter. And making imperial alts so that you can further insult your opponents on the imperial fleet general channel is completely unnecessary.
