With regards to premades, I again want to clarify a few things:

The only difference between a premade and non-premade is familiarity and coordination. Neither of those are exclusive to premades. Maybe tougher to achieve, but it is within the realm of possibility.
Most premades are veteran players who - in Shatter's case - have a deeper understanding of the mode, and the various ways to score. If there's no ice to score on, we actively fight other teams, generally the lead team, or whomever attempts to take the offensive against us. I personally am always scanning the field for prime targets like battle highs or healers, or weakened targets to secure points from. That might sound cruel, but it's simply taking advantage of the various ways to score. And it needs to be noted that the descriptions for all Frontlines modes include "as well as defeating enemy players."
