Lower the Play Rounds daily amount

[Terran]

I can do pretty much all of the dailies in an hour to an hour and a half, and the only reason it takes that long is due to the "Play X time" daily. Which is usually 60-90 minutes or so. But the play X rounds is usually 50+, and that takes about 3+ hours for me most of the time. Today I've played 3 hours on FRG and I'm only 42/54 of the daily, but I long since completed the rest. Why have a playtime AND play round daily challenge?
It should be 25-30.
