There you are utterly wrong. At best it's different but not easier. Depending on heavily how your matchmaking is.

For example Aion, it had all kind of group pvp from 6vs6 , 12 vs 12 , 24 vs 24 etc. Despite having a more or less okish balance between classes, the matches that were even you could count on fingers.
Why? Because you can't influence the matchmaking and the skill of players. This is idea behind having 3 sides to counter these problems.

Is it better? Who knows. But the influence on balancing isn't so different. A disadvantage is clearly that the battleground can get very chaotic with having 3 "groups".
