Zerg fights are annoying. You're respawn time gets too high, you have to deal with countless noobs shooting you instead of the enemy. The frames are far too low. Any vehicle but a tank is owned because the enemy has such an abundance of av now.
With platoon sized fights, you're actually pitting skill against skill, you get an abundance of kills. And if you're on the defensive, you get to push your self to the limits because you'll have 2-1/4-1 odds against you all the time. Forces you to think to win and not charge head first "guns ablaze."
