With current shammy DPS you can burn LessRabi pretty quickly before he is doing his transform too fast -- the first 2-3 times you can wind/earthshock it (I wouldn't flameshock at all one one guy at least to keep the CD always up) and with lust at start you should be able to burn him fast enough.

There IS a trick however, dunno if it was fixed in 3.08 but if you have a rogue or mage what you do is stack your guys on one side of the room away from the stairs up, have a rogue or mage pull the boss from the other side (near stairs up) and run up the stairs quite a bit, as the boss runs towards the puller he will transform after a little bit, at that point the mage/rogue vanish/invis, at the same time the rest of the team moves into the path back and aggros the boss (now a rhino) while he's running back. The mage/rogue runs back and rejoins the fight, you do the entire thing while he is in rhino form and you get the achievement since he technically didn't "change" the entire fight. Of course, this might have been fixed in 3.08.

I'll try out the Nexus tips next time I'm over there. I also am curious if anyone is doing heroic occulus after the vehicle changes, haven't heard a thing on this forum about that instance.

I spent 2-3 hours today in UP trying to get those achievements, the first boss one was easy, just pulled a abom to the alter and DPSed it down to 20% or so before switching to boss. Wiped 5-6 times on skadi trying to do the "reset, fight in room" method, was able to bring him down every time in one pass but too many adds were up and it was too chaotic, will have to revisit that one later -- just did it the regular way of moving forward slowly and brought him down (no drake, qq).
By the way, the speed of his cast is dependant on his health - it's not on a timer. Transform below 30ish percent has a casttime of like 0.5 percent, which is why a mage (or no lag, a little luck and very good reflexes) is a pre-requisite. It's def. doable though - and easier than most of the achievements in the "medium" category.
