Hit the XP cap today too, almost done with the "mandatory" part of the grind (canonically big mags for Vivi, Cheeta and APC10; ADS speed grips for ARs with heavy barrels and all LMGs; ADS bolts, rangefinders, long barrels and long-range ammo for snipers, etc), all that's left is
>20-point muzzle brakes for all ARs that aren't the G36A4 (got it while unlocking the Andoris barrel) and A-545 (for some fucking reason these brakes only unlock at lvl 30+ for every AR that isn't the A-545)
>20-point muzzle brakes for Lainie, MP5, MPX and P90
>ADS speed grip for the L85A3 to offset the heavy barrel's downside
>ADS speed grips for the Minimi Mk3 and Ultimax 100
>headshot ammo for the SVCh
Hopefully I can make it tomorrow and be DONE with the grind. I don't care enough to also unlock good suppressors, which are mid-to-high 30s unlocks on every gun. And hopefully these experiences will keep popping up in the future so leveling new guns won't be a bitch.
