Well, i'll say from the convo posted alone, Vahnati looks like the typical unloyal score whore. It takes a good leader to keep those kind of players in check, or an extremely passive team. Now, I understand that sometimes getting sniped on things constantly can build up and lead to a blowout, but from what I just read, it seems like he just had his panties in a bunch.
I've played with Energy multiple times. He is ALWAYS willing to back down on a conquer or wreck. I've never seen him once fight someone who simply asked him. He even said he'd back down in that chat. It's obvious Vahnati had no respect for his teammates in the first place if he didn't have the decency to even ask before accusing.
