I think they did increase the hitbox size - didn´t they? This actually should pay off for the current spread at least a little bit. In order to judge properly, if more or less spread is needed, we should wait until most of the variety in weapons is set in stone. I would actually like to see it little bit smaller, but I don´t know if I would actually be able to tell the difference. What is much more annoying then the spread however, is the mouse delay… But for how long are we saying this already?
Besides that, a lot of people rage for no reason when they don´t hit. It´s sometimes hard to tell, if you are really aiming at the head, or just slightly next to it. That´s what I learned while playing with relatively low spread guns in fast paced games at least.
