Path of Frost Nef Encounter Bug

My raid started reliable Nef attempts 3 weeks ago, and our first two weeks we experienced a weird problem where Onyxia would randomly turn and shadowflame the raid, even though nobody was close to the tank on threat. I'd been using PoF to negate the initial fall damage, but last night a pug told us that path had been causing weird issues with this encounter. I stopped using it, and we didn't experience the bug at all last night.

Anyone else seen this? Just thought it would be useful to know, as glyphed path is somewhat useful for the start of the fight.
Levitate would cause Nef to turn around and punch people to death. Best just not to use that kind of stuff.
We did have a priest using Lev as well, so maybe it wasn't completely my fault for wiping us 30 seconds into the fight multiple times...
this is a known issue. as far as i know, it is still bugged to do that. so dont worry about the little fall damage, its too bad it does this crazy thing.
Any sort of character height alteration mechanic (PoF. Levitate) will cause issues on platform fights. Because the platform you fight on moves up and down it creates glotches when anyone uses those skills. i still get griefed about causing wipes for the first 3 nights of heroic progression...
Wouldn't PoF break on damage anyways?

I'm not sure how you're managing to make it to the first flame breath without taking any damage.

He's frost/unholy, so he wouldnt be tanking Ony.
