The matchmaking is much faster when the teams are all broken up by multiples of 5's. But not only this, the matchmaking is MUCH MORE FAIR when it is broken up by 5's.
Because there are more teams in the queue it allows the engine to choose matches that are more closely matched by monster power. This means overall, wars will be more fair and more fun.
Once you have it to where you have to find a team with your number of players, then the lack of choice inevitably puts teams at further odds from one another in their monster power.
Please bring the matchmaking by 5's back. Only a few, and the weakest, players had to sit out and it encourages teams to keep recruiting and staying active. Thank you
