I did. And no, it really wasn't.
I know a lot of folks that didn't do them at all, or only ran premade groups for heroics.
i also personally know a bunch of people that had others do their PGs for them.
You also didn't notice that most of the folks complaining about them played certain classes. Certain classes that had weaknesses that eventually got adjusted.
And most of the gimmicks used in PGs(ambers being the biggest ones) have no place in the actual content. Even at minimum gear you could brute force the entire thing.
Then again...
It wasn't really challenging until you did endless.

My main screwup at the end there was assuming my aoe would hit the idiot standing in the middle. -_-
