I agree with Acornie the term "tryhard" is probably overused at this point. There are things in APB that are annoying and can be abused, fortunately or unfortunately depending on which side you're on. Two things I notice a lot are car "rushing" and crouch "spamming" to avoid shots; however, with the way the game is designed it's inevitable people will find and use things that give them an advantage. There are weapons and mechanics that need tweaks, absolutely, but there always is and always will be things people use that are considered part of the "meta" of a game no matter how frustrating it may or may not be for others.
Granted you die enough to remote detonation or the firebomb in the spawn on Baylan and you can only laugh, or cry depending, at the absurdity at some point.
