Just going to throw this out there.
BW's are easier than Fed's when you don't have players being stupid by pushing the cops who are supposed to be attacking you. You're crazy if you think you need 30 people to do a Federal Event, and if you need that many people, clearly the majority will play dumb and push.
Also going to through this out there, Prime is the reason gang life is not in a great position right now. Without going fully in depth, think about Prime like the Golden State Warriors or the New York Yankees. All the best players went there because they saw them dominate. Then some got caught using steroids(pulldowns or DDOS'ing) like A-Rod, Andy Petite, and Roger Clemens(Tiger, Haiwood, etc.) Then what ever was left grew massive ego's because of how good they once were. Now, it's a revolving cycle of gang's popping up Triden, Apes, etc. that never last because of someones ego. Gang life is making a step in the right direction by going back to smaller gangs with a couple of good players. If you were around for that time, it was literally the best gang life had ever been. You had gangs like VX, Tree, MC, Ti, Evolved, Detectives, Pillow, BFO, DB, Los Zetas, X-Rated. The list goes on and on.
So in conclusion, Prime is the reason for both the rise and decline of Federal Events being done. Not blaming the members or former members of Prime but explaining how we got to where we are today.
