never did the league so yea.
Trying to complete betrayal benches challenge, there a tip to getting these guys in the right spots?

You gotta kill the ones you want promoted and cage anyone you dont want as leader.

delirium gives so much currency its not even worth your time doing betrayal/incursion

doing it for the challenge..

You can also start doing other syndicates and ignoring the one you have nearly done until you get the option to switch the guy you need to it.

I dont know him, but he cant be worse than vajini

I just gave up and did another challenge. I just wanted the wing and quit the league haha

if you really need someone in a specific spot you can run the masterminds lair when its ready.

Then you will start over with all your masters, all you have to do is keep ignoring them untill they spawn in the location you want

i love betrayal
love free exalt slams, white sockets and pure chayula stones ^ ^
aaaaaaaalllll day baby

Maybe this will help you. If you need to make a decision after beating them.
