In order to queue for Molten Core LFR you must have an item level of at least 615. If you're not level 100 yet, don't fret. This event is ongoing until January 5, 2015 and I suspect many will continue to farm it for chances at Hatespark the Tiny and Flames of Ragnaros, both of which are not guaranteed drops.
I'll admit that when I first went in, I expected this to be a complete pushover. However, I forgot how hard it is to organize a group of 40 people. Almost everyone inside is just barely making the ilvl 615 requirement to boot. People are used to soloing this for transmog gear and it can result in many wipes. It took my group nearly 2 hours to clear the whole raid. My first group didn't even make it past the first boss.
