With how unbalanced, easy to team stack, and RNG Frontlines is, SE should probably just stop tracking the win/loss rate for the game mode. By all means the total count of wins can and should still be tracked for achievements, but there's no reason to track and show total games and losses as well. It's only serves as something that encourages toxic behavior from the groups of PvPers that intentionally stack matches so they can brag about having unrealistically high win ratios. And yeah, it won't stop premades entirely, but it would at least take away some of the perceived incentive for them to go out of their way to be toxic in the game mode.
