I have been playing for quite some time in some grinding games, I will not mention names but mainly I used to playing over 500 hrs and I almost got everything in those games.
In APB, the progression is way too slow, you achieve things quite slower than other games, I once played for half a year to maybe get few skins to my weapons (non-p2w) and the maximum things you can achieve in this game makes you be less worthy over other p2w people, which currently gives them an advantage, but well. that's the game, I hope someday it will change and bring more players around.
