1. You can't settle into a server knowing exactly what map rotation you will be playing for the next few hours.
2. You end up playing a completely random map rotation, sometimes even playing the same map twice.
3. You can't play with the same big group of people in a server for multiple games in a row so you loose all the comradery and rivalry that goes along with that.
4. The whole experience now has no structure and after each round you feel like you are just leaving the server and hitting a big 'random' button to decide what map/server you are going to play next. If instead of adding this new 'balancer' if DICE had literally added that aforementioned 'random' button, how many people would have pressed it after EVERY single round? None, that's how many. But alas now it's being pressed for us at the end of every around whether we like it or not.
What an absolute game killing mechanic. I wonder what made them add it.... Oh wait, it's almost Christmas so we were due some kind of massive game killing mechanic from DICE, I almost forgot for a second about the holiday tradition where they break the game before Christmas to 'help the new players or something' causing outcry from the loyal fanbase which eventually makes DICE reverse the change but not before they adequately ruined the gameplay experience for the holiday period. The big question this time is, is there enough of a community left to cry out this time?
