Logic behind monthly challenges?

January, win 70 games and earn 15000 xp.

February, win 30 games and earn 30000 xp.

Not a big deal but it just seems like these challenges are randomly made up without any critical thought/logic.

Yeah, I noticed that recent challenges are becoming a lot more generous with XP. Even Wargames and Spops are offering rewards in the thousands and ten-thousands ranges now.

(And just after I hit sr130 - ^%$%$^%^$!)

i just wish they would stop making the monthly so damn easy. i loved the win 117 games in a month one. but seriously, win 30 games? win a single game once a day for the monthly isnt much of a challenge. i view the daily, weekly, and monthly as something that should be progressive difficult.
