If it takes me 15 body hits or 3 headshots to hit one guy with mid 40 armor
Now this is complete bull.
I have (EDIT: Had, recently deleted b/c of boring) an archer stf (7 PD) and it takes me like 3-6 hits (it seems extremely random) to the body to down most mid infantry.
And I've yet to make one headshot that didn't kill. On my main I've survived
one since the patch, and that was a long-range shot (like 40 m) from a HA, which still took 85%.
