I haven't played a snipe capable character yet since joining the server, so I can't comment on the i24 implantation. Overall, I think this system has some promise but definitely needs some tweaks. the quick snipe range should probably be 90' and the out of combat timer is a bit on the long side for my tastes, and I am a patient player.
As a content creator I've come to understand sometimes you have to get something wrong in order to get it right in the end. Let's remember this is a beta not a pre-release preview. The numbers aren't set in stone.
