I've yet to try a heroic, just finishing up the lvl 85 zones, need a few more gear points before i can queue.

I always thought I was decent at multi-boxing, but then would see someone say X or Y boss was easy while I was wiping on it. I came into Cata poor so haven't been able to buy any gear upgrades at lvl 85. I'm not finding the lvl 85 normals easy, so I imagine my progression will mostly halt once I start trying heroics.

I've gone through this is fun to I F#$king hate this wanting to through my keyboard on the floor. The latest keyboard throwing almost occurred after I added a new ground based spell and most of screwed something up (again) as mid way through the fight I notice my guys wouldn't auto follow were running in different directions etc.

Anyway, I hear ya, I basically set the number of wipes I will do, then after that I run dailies , play solo, quest etc. After a bit I'm ready to try again.

on the bright side my skill boxing is way better than before the exp. I can now CC without blinking, moving is getting pretty good.

Though I'm still not with the uber boxers, I read Toned's description of the first boss in Halls of Origination heroic and though, "Um, you did what?" Not thinking I could even try that yet...

I've been saving all the melee shaman gear while I've been dungeon crawling as I think that might be fun to try as a solo char.

As others said, I would take a break, or play solo and then revist again later.
