Power Level Nerf/fix?

After a few weeks I finally got some more time to go power level up a new team. Went to Ruby Sanctum and summoned my level 4 hunters, enter 25 man Ruby Sanctum with my 100 Monk. Proceed to follow monk inside - And the level too low to enter message pops up!!

Apparently this was still working as of 2/2/2015 according to a comment in a youtube video posted on 2/1/2015. And 2/3 just happened to be a patch day....

So did we finally just get stealth nerfed?

If so, I'm at a loss for how to level up a hunter team. I really do not want to do questing. I hate it, especially with having to pick stuff up. Any other ideas of what to do?

I'm guessing just the old fashioned way of getting to level 10 and instance grind?

Ruby Sanctum allowed this? Interesting, its not a nerf if so its a fix.
