Why don't we just set up a tournament within Olympus, gang wars in a way and set up a bracket. As we do this, Asylum does the same within their server. There will be a 1st, 2nd, and 3rd place. These guys move on.
Top 3 gangs from Olympus then do a draft, same for Asylum. The way the draft will work is, 1st place team elects a captain and he then picks from the 3 gangs. Obviously it will be hard to do since they'd prob like to keep their whole gang. Have to find some better idea for this but you get the idea.
Basically forming an Olympus/Asylum All Star Gang and fight it out for a huge reward. This way "throwing" won't be a thing since there will be a reputation on the line of which is better Olympus or Asylum.
