Bruh, APB is not a complex game to do this stuff in due to lack of interiors and flanking opportunities; ~3 people can easily corner spawns. Quite frankly, many of the points are absolute death traps and funnel you in from a couple directions to begin with. New players won't know this though and even experienced players become very predictable.
Ranting at Revo isn't going to change the fact that APB has a niche market, and therefore will have niche gamers who spend most of their time in it and learn these things. Even to this day, I'm not really sure there's a game quite like it, which is kind of shocking, tbh...
