I have been able to follow the random dungeon since it was in the game, except for the odd 80 speed bump due to gear when you have to quest a bit, cannot queue for WOLK and you cannot queue for Cata (same for MoP), but it's just a few hours and your back to grinding dungeons.

I would agree that the first water world boss is tough, but some comps or macros (rally to warlock after teleport) or rally to alternate character can make things pretty easy. The last beer boss is really comp specific on if its 'easy' or not it seems. But if you check out some of the challenge videos, use of the pillar and such can really help control the first stages.

Some of the people I heal for that are boxing don't use crowd control and just zerg through all instances, normally don't run with a dedicated healer. I find that odd, they really have problems getting badges and clearing heroics.

I have never heard of Occulus specific macros, that place i so odd.
