As a swarm player, I tend not to cut the corners but to play devils advocate here:
If you have a problem with your swarm opponent grouping his movements and actions and cutting corners and not following the strictest of rules: How will you feel when your opponent adheres to your strict requirements but this causes him to take longer during the game, not an intentional delay just normal delay for having more ships (though I often find myself with 8 ships ready before my opponent who has 3-4 ships)? This delay in the game could be the difference between you scoring a modified or full win for the round. Just a thought...
I'm sure this will sound kinda harsh but it's not mean to be. If you are unable to follow the rules and it is constantly causing you to get modified wins( and that bothers you), time to research a new squad or tactics. The time restrictions for tournament play tend to push for an offensive squad. Eliminating all the ships from the other player seems to happen more often then not, from my experience as both a player and TO. Bending the rules should never have to happen for the sake of time.
