the amount of headshots is getting ridiculous, seriously
I haven't played lately, but I think you can blame the archers adaptding to the archery nerfs, especially the body damage nerf. They simply get better. I mean, the amount of successfull blocks went up since cRPG started as well, and we are now on a ridiculous level of blocking.
I don't want to attack you in any way, I just don't think the devs increase the head hitbox. So higher skill would be the only explanation left.
