In short: I hate it.
I never had any problems with the old system: I got into the weaker team for one map, then into the stronger the next. Some times x1 for several rounds, but also very often long x5 strikes. And I had allways fun trying to do good despite being on the weaker team. And sometimes even the supposed weaker team could surprise the other by a change of tactic (read: change running direction).
That is gone with the new system, you get switched all the time and - like in siege - you will be glad to have x5 for one or maximum two rounds. What makes this worse is that you no longer know which player is on your side and I also get confused on which spawn I start. Before the patch (after the first round) you knew: ah there is this extreme good cav on the enemy team, have an eye on him. Or there is this guy to stick with, and so on. Now that is totally gone, and when I get switched 4 times on 1 map I don't even bother to think on which side I am and where I go, just charge and be done.
