When i was playing i noticed that the challenges only give 7K instead of 27K. I started playing last season so o still don’t know a lot, but wouldn’t that make it harder to unlock new agents?

I've been playing for around a month and a half and I snagged my 4th ever ace recently and clipped it! It was probably my best ace to date, and there was no hp lost in the end so I'm pretty proud of it!
