I no longer recognize my bad red men...

I'm making this post to vent my frustration, i was summoned as a blue to the Church of Elleh by two gankers, i left their world and came to help my red fellow as an invader.
I sent him a message to join me and take the gankers by surprise, he followed me to the Agheel swamp and took advantage of a moment of inattention to backstab and kill me.
I guess this guy was with the gankers, and that saddens me...
