Not particularly. If you're still grinding wins for rewards, it's worth it. If you're grinding to hit a new highest rank, there isn't too much reason.
note that this reset only affects players over Diamond 1
So if you arent D1, Master, or Grandmaster - feel free to play all day with no worries

MMR Resets for players 2750 or higher back to 2750 (This used to be 2400 but top end players felt their matches were too volatile at 2400)
Rank Resets for D1, Masters, GM
