Milan died because he was kicked and lost his army to one of our armies. We had consensus to attack LAN when we did, Only dissent came from Psi and Leo. It's unfair that 20 people wanted to do something but because one guy, who never really led the alliance in actual war, didn't want to do it.
Backstabbing is a part of BD, everyone does it. We also had to in order to even have a chance at beating an alliance with 500 more power than we had.
