Why happened to the spartan ops challenges?!

A while ago(I’m talking months) the Spartan ops challenges would give 20.000cr for doing stuff like: kill 2,000 grunts but now when you, kill 10,000 grunts it only gives you 8.000! What is up?

The rewards are randomly picked.

Didn’t you notice that the same thing happened with the War Games challenges? Their rewards used to be thousands of XP, but now you’re lucky if it reaches 1,500 XP.

343i have effectively eliminated the Challenge system. Now watch what happens to the Commendations…

But seriously, it’s cuz players kept complaining about achieving max rank. This is just a poor way to halt progress. Add more ranks! Or make them more proper cuz they signify only playtime.
