If I do something like that, I will explain my intentions. I don't type fast, and generally don't in game chat. My map usually loads really late and I only get a couple seconds before the battle starts.
I realized this weekend that the Tiger P does way better as a heavily armored TD than a brawler tank and I was using it that way. Rubbed a few the wrong way and if I caught too much flak I just drove to the battle without firing a shot and died. I would then point out how well that worked for the loudmouths.
Sounds like the E 75 was just being a dick. It can happen. I don't let it get to me.
