I'm probably starting to sound like a broken record, but I really do still have a rabid dislike of heroics.
They add all these raid inspired mechanics into fights that you THOUGHT you knew, so now you have to put up with dying umpteen whatever times to learn a fight if you are like me and mentally, as a result of a Traumatic Brain Injury (TBI) thanks to a drunk driver, have difficulty adjusting to dramatic changes or too much "stuff" going on at once. Problem is, most LFD groups do not like wiping multiple times.
So 9 times out of 10 when I queue up for a heroic there are multiple wipes on some boss, a lot of mutual bitching about "do this, not that" and "don't stand in the bad stuff" and the group falling apart, or I just give up because I'll get too frustrated if I keep trying and failing. I move out of 'bad stuff' but the problem is, the damage is so great that if you get hit by even a little bit of the 'bad stuff'' then you are toast.
I get frustrated at the people in Blizzard forums who love to call people "baddies" who just want to be carried if they post something like this blog post. I've never wanted to be carried.
Then they accuse you of calling for encounter to be nerfed. I've wished some encounters would get nerfed, but I'd rather LEARN them!
I had some great experiences in Wrath with raid groups doing Naxx. The people leading had patience. Patience to EXPLAIN things. Patience to keep at things because we were improving.
People love to suggest I watch encounter videos on tankspot or whatever. Watching videos doesn't cut it, doing the encounter is the best way I learn how to do encounters on any given class. If watching videos was enough, I'd be able to play guitar or hit a baseball, but life don't work like that.
Blizzard is under some misguided notion that the cataclysm heroics will self-nerf as people get higher item level gear. I suppose with some classes, there may be some truth to it. Not with my mage. Poor squishy troll has serious issues living through many of the heroic encounters in Cataclysm. /sigh
