So I have been enjoying going through and trying to complete the challenges this season, then I noticed while trying to complete the warzone challenges for the 3rd and 5th agent tiers I noticed it says get to warzone stage 50, and warzone stage 110. does this refer to the actual warzone stage or the number of battles you have completed in the warzone? cause if its stage I think I will do these challenges at a different time cause thats 500 and 1100 missions respectively as far as i can tell.
