How do I level up extremely fast without having to go through the bs of doing challenges
Don’t do Grifball cause you’ll be a dirty booster 
Firefight is a really good was of getting Cr, last I remember you get around 2000 Cr each Completion, and any Challenge that requires Firefight matchmaking will increase your earnings when you complete them.
I went from Captain Grade 3 to almost Lt. Colonel from it, now I’m General Grade 4 about to be a Field Marshall
And Requires playing the game a lot as well
Thxs bro
just do griffball
I used Team Slayer to grind a bit, but then i switched over to Firefight. Less Armor Locke spam lol
