I solo'd/tried a lot of bosses on live and beta of Wotlk, cataclysm and MoP raids, and extrapolated data.
First, the bugs I encountered during soloing sessions:
-Mend/rez pet: many bugs.
First, it sometimes switches to rez pet while your pet is alive - if it happens, you can't cast mend pet on the move and have to stop, cast, then start moving again. If you're trying to kite a boss/add, it can wipe you.
Also, if stampede is active you can't rez your pet.
Finally there's a bug shared with spirit bond: it heals the pet for 5%/sec (respectively 2% sec) despite the blood of the rhino talent and glyph of animal bond (+40%/+10% healing received). Also, the glyph didn't work on me - spirit bond healed me for 2% and not 2,2%.
Therefore there may be a bug that makes it so that +healing received% does not affect percentage-based heals. If it's the case, it's a nasty bug for everyone. If it's just hunters that are victims of this bug, it's a 35,5% loss for pet survivability and a 9,1% loss for hunters, and I really noticed it during my beta adventures.
Other bugs I noticed:
Gunship battle was really bugged. Maybe it's because I feigned death at the start? Either way, there were no adds at the start, only on sergeant appeared in 2 portals, no mages or goblins, and 4 axethrowers that didn't move into position.
Many debuffs in old instances still dealt full damage to me - examples: blackout (theralion and valiona, OS'ed me even in 25-man mode with 50% deterrence), the debuff in frostmourne on LK 25H, the ice sphere's debuff on LK 25H, the shadow prison on blood princes, and the magic debuff on ignacious/feludius.
