Im forgetting, I heard next Major Patch is Later next month?
If I hardcore Grind CC and supplement it with Frontlines, how quickly can I get to lv 25?

I think I have the first layer complete. I think thats Lv10.
Just about done with my Apex Legends Battlepass, and I have 2 months left and 75% through Season 3 of Modern Warfare 2: Remake.
So after Apex I should have nothing distracting me. But Im wondering how hard I need to grind (giggity)
