Yes, Molten Core LFR will grant Hydraxian Waterlords reputation

I'm pretty excited about the upcoming 10th Anniversary Molten Core LFR, but I have to admit, of all the reasons I have to be excited about that, the idea that it would be a way to gather Hydraxian Waterlords reputation would have been absolutely on the bottom of the list. However, some of you apparently care about this, and now it's official - Crithto has confirmed that yes, Virginia, there is a Hydraxian Waterlords Reputation Santa Claus. So there you have it.

Now, when I ran Molten Core, back in the day, you needed that rep to get the Aqual Quintessence you needed to douse the runes. And you needed one Quintessence per rune, so several people in your raid had to be gathering rep with them in order to get enough to complete the raid! You kids today, you don't even need to march 40 people through Blackrock Depths to get them to the Raid entrance inside the very base of the dungeon! Now (well, soon) you just queue up in LFR and get all the sweet Hydraxian Waterlords reputation you want, and you don't even need it for anything!

I'll be over here in my rocking chair.
