The basic idea is that the guild is split into two squadrons, red and gold, each containing roughly half of the total number of members we have at any given time. They alternate going for high scores and going for an artificial lower target. This allows everyone more opportunity to use more of their roster 50% of the time, as opposed to being limited to 1 fight every time (or sometimes 0 if an FFA is done).
The writeup is very long and I don't want to reformat it a second time, so if interested please see the details on the SWGOH subreddit:
Quit 7/14/16. Best of luck to all of you.
