The following is aimed to people who dislike/hate this announcement :
Like you (if you feel concerned), I dislike that CS:GO skin system with those crates/keys stuff.
Will I stop playing KF2 for that reason ? No.
Will I still support TWI ? Yes.
Like it has been mentioned on the website and mentioned here again, you are NOT forced to buy and use the skins. I know some people who played and enjoyed TF2/CS:GO/PAYDAY 2 with the default weapons only (even if gameplay stats changes were involved) and they will do the same with KF2.
You got a weapon skin crate ? Give it to an friend who is interested in or just sell it, done.
I would very like to thank TWI so much for making all this stuff cosmetic only, I (and I guess a lot of players) wouldn't want to have something like "PAYDAY 2 Black Market Update" where cosmetics boost stats (yes, buying the drill (key) to open the safe (crate) and get a white AK that add +4 stability. I don't see the relation between a painting improving weapon stability).
To make this short, if you stop playing KF2 because of this, then stop playing any game. You are acting like those CS:GO players who cry and rage because of the FN P90, G3SG-1 and FN SCAR (the "autonoobs")
