I know this is old, but it has gotten much worse on Light. The queues generally start at 4pm and end at 6pm ST, Just look at the frontline rankings on the NA DC compared to Light and Chaos, they have people with more than triple the wins because they have more matches played, for months now the top players with the most wins on frontlines have like 17 wins on light, look on on the NA dc for the weekly rankings it's always multiple players 60+wins.
