I am actually not sure if developers wanted this garbage to be in the game, or they just didn't think about it, and now we are like Oh hey, unlike a lot of games out there, in this one there is absolutely no penalty for bobbing up and down as far as you can.
Like yeah, this suppose to be fast paced game focused on movement, but crouch spamming is just stupid.
If they wanted it to be in their game, then it's sad, if they didn't, then I hope they will fix it despite a lot of people bitching because they came to rely on it by now.
