The nerfs were applied over several patches, the most notable would be the changes to field scout and final round qhen tTK came out. As for the double down perk that came out arround the same time as HoW And finaly as for your effirdeets spear comparison. Efrideets spear is a max impact sniper rifle variant, where as supremacy is a near max. This is relevant as the prior sniper arcgetype has a lower base count for ammo than the later.(12Vs18) Since the high impact snipers got less from FS than the lower models(gaining 1 extra shot per mag) where the slightly lower impact models got 2. The ammo count becomes 16Vs24. And finaly the double down nerf was applied around the time HoW dropped which is also when we started to see effrideets spear. So effrideets snopers only ever fot the x1.5 bonus(i point this out in my orriginal post) meaning effrideets capped at 24 vs supremacy pre nerfs 48. Warning:math [spoiler]16(1.5)=16+8=24 24(2.0)=24x2=48[/spoiler] After the DD nerf it dropped its ammo count down to 36 and with tTK changes to field scout it dropped further to 24.
