"Good players benefit more from checkmate's special ammo meter"
You listed this under "Balance Issues" which is very weird considering the system is put in place to promote primary weapons and of course a better player will score more kills with primaries, than players who just know how to run in with a shotgun or cheese kills with any other special ammo weapon.
Are you going to tie special ammo generation to K/D next? How much lower does the skill ceiling need to sink?
“Snowballing” mechanics just exaggerate the skill gap.
One way that could better demonstrate skill would be to give players a set amount of special to use at the start of each match and no more. When everyone is given an equal amount at the same time, the skill is in using it most effectively, when you really need to.
Special seems to be a bit of a mess at the moment and not having it sorted in time for TFS is bad news.
