My current main is a ret pally. I have not had that experience, but mine is only a level 74, so no heroics.... but that shouldn't matter too much as most things are scaled. I have other toons who have played in heroics, pre patch. But I AM surprised at the damage I am now taking. Non casters of equal level can actually almost get me down to half HP. OTOH, Art of War, followed by Hammer of Wrath is incredible. I can get 13K damage dealt in 2 seconds.

For me, that's pretty darn good.
I guess the whole game is down... can't sign on, and can't even get on the Blizzard forums. I don't know if this is really true, but this feels like the worst it has ever been, post patch. Part of that may be my Kapersky Internet Security though. It REALLY hates WoW. To get any kind of update I have to turn it off during the update.
On another note, I have been trying to get those achievements by fishing the Dalaran fountain - the ones with all the coins. I have it all done except for the one gold coin - the coin of Arugal. I have had all of them done for about 2 weeks. Since then I have fished anout 3 hours for that stupid coin and still no luck. I bet I put 7 hours into this achievement, which is dumb, but I did level fishing to 450 doing it.
Anyway, in local chat I mentioned that I didn't have this coin yet, and the guy next to me says "If they weren't soulbound, I would give you one of the 4 I have right now."
This morning I went into a PvP area for a daily and my PvP would not turn off after the quest. I even checked that PvP was on disable. Anyway, I went farming thorium in the crater, and 2 different Horde kept killing me.
I had to log out to get PvP turned off.
