Fully agree with this. Queued up with a friend all day yesterday to get the garo gear/title/mount and all 33 Frontlines was Shatter. I honestly miss Secure because it's been years, and I've never been able to play Seize because I wasn't subbed then, so now those achievements are looking almost impossible. Shatter isn't bad at all, but you have 2 other maps, let it rotate to keep things fresh.
