What about Razergore?
I was hearing some people going "you can't" and some said "I did", and then a Blizz guy said there's a new supposed tactic solo peeps are supposed to use, but I didn't quite understand what they were talking about (I've only seen the fight once).
I'd like to get the Judgment set (if I can find a pair of legs that goes along with the rest of the set; I ain't wearing no dress), so I'm kinda interested in that.
Here is a video on it. Seems infinitely easier.
In my personal experience, Razorgore is a chump. Took me two tries, because the first time I wasn't really understanding what I was supposed to do (haven't run BWL in like 3-4 years). Nailed it the second time without issue. As long as you can destroy the eggs within two orb cycles, you should have no issue.
C'thun is ridiculously easy as well. Killed him last night after being sucked down to his stomach twice. If I had run as my DPS spec instead of tank, I could have killed him with only one stomach trip.
