Actually the number-balancing i did was around Suicidal and HoE, while trying to make it not too useless offperk, so especially Support Specialists would be able to use the rifle quite well too (since that was the original perk it was intended for)
Currently, FPs takes 2 headshots on 4man HoE and up higher.
I will try and bring down the base damage quite a big notch though, so it's not massively overpowered on bodyshots and on lower levels (hard and down), BUT i will still make it so that on 6-man HoE, a Fleshie is almost EXACTLY 2-headshotted, but only for a level 6 (maybe 5 too) Sharpshooter.
It still needs a somewhat high damage though, to make it decently useful against Scrakes, even offperk (will try make it to still be a 1-headshot on Scrakes for a highlevel Sharpie on 6-man HoE)
It's easier said than done though...
I will work on new numbers when i get home from work.
