It can be weird. I wasn't getting any games as Maelstrom on Primal before Garo. Now I queue as Freelancer & usually get a game in less than 10 minutes. However, over the weekend I had huge queues, quite a few I cancelled after 30mins sitting at "approx 7mins" or so. I did see a few 24 man Shatters though, which is unusual. Last night (Sunday) it wasn't too bad again. There seems to be a very unusual 'prime time' for Frontlines that doesn't correspond with the rest of the game.
