Word is that this new flame and frost instance will be a limited-time deal, much like just about everything else that’s been added to the game lately.
This is a bad, bad move. How is this game supposed to look like it’s growing and being developed if nothing ever stays? Person A quits before flame and frost. Person A decides to come back after Flame and Frost has been turned off. Person A sees no new content. “Boo, this game doesn’t get development at all!”
I know that it, personally, leaves a bad taste in my mouth when we’re given content that so much dev-time was devoted to only to have much of it be temporary. Please ensure that at least the 5-man dungeon is permanent.
