Hi I been grenade grinding and I only need to fill 2 more trees then I am done with my fs xp i was wondering is scout xp with master riflemen just as good as grenade grinding? I know it'll save me a lot of money since i use proton grenades to grind lol. Anyone got any information on them for me plz?
