8 vs 8 is fun, certainly, but the clusterf*ck of things happening on the screen takes away from it a bit. There's a ridiculous amount of floating text and far less emphasis on actually doing your job or playing tactically. Most people just jump the nearest target and go crazy, regardless of what their job is or if it's the smart thing to do.

By comparison, 4 vs 4 feels tighter and has a stronger emphasis on actual player skill. That emphasis makes the rounds much more intimidating to get into, but winning is far more satisfying.
