You were observed ignoring the team over multiple AB's. You would que for AB, then ignore the team and fish. When the enemy would come to you, instead of participating and defending the capture point you would continue to fish. You are basically an AFK player, but almost worse, you are griefing your team mates.
A warning was fair. If done again, a few day ban would be adequate.
Please stop griefing your faction, and please stop trolling these forums.
