My motivation is to keep this world alive and actually fight an enemy that will fight back. Most of BoH quit a long time ago, and hasn't been a challenge since Wisdom collapsed.
So, you're an allied player because you want to keep this world alive and fight an enemy that will fight back and there is no challenge in BoH.
You're also that much want to fight that you don't uncover your identity as that could give you some fight.
What a series of oxcy-morons again!
