One of the things that immediately escapes players is that it is only natural that a defense be mounted against the stronger assault. I usually hear the complaint that the opposing teams are not fighting each other "as usual." Well, when you are outnumbered you will have to either show up to defend, attack, or you will get rolled. So once again the enemy 'truce' is a myth for the most part.
Then there is the 'ENY whine.' This complainer is a knight.

It's human nature to complain when you are unhappy, but a little fact checking might save you some anguish and perhaps help to keep customer satisfaction higher.
I see this on Steam all the time. Train Simulator, for instance, has been updated annually without any additional cost to the customer. Yet, every year the customers will mount a complaint campaign claiming that the new update is the same old game (despite all the fixes). IT'S FREE!
Here the users are complaining about their inability to find a fight, while they are fighting, and yet the idea is for fewer teams? Think about that and you will see that two teams will create a situation in where the fights really will dry up.
