I've inserted this into server, tested a bit ... Usually, people are lazy to wait 1-2 mins to download all files. But, on side that, I've noticed people arguing about changed way of shooting. They say it's similar to CSGO and they unlike it so they leave.
Day by day, people leaving because they dislike it and they say it would be much better if that could be turned off.
Is there a way to add cvar to set recoil and spread to be like in CS 1.6 ? I, personally think the same. Recoil and spread is what keeps 1.6 running. It's core of this game.
