I don't doubt you for one second. (I did a lot of TL for Wymn) BUT, I can only stand around looking for a group for so long before I log off.
I'm no rookie either. I know my class very well, I put out amazing dps, almost full T4, and I follow instructions, but I can't find a group to join unless it is yag loops/flame/vortex/palace/hoc rare farm mind-numbing-let's-do-this-for-the-millionth-time.
SOOOOOO, I log off and I stopped trying a few days ago. Hell, I couldn't even find enough people to do a Xib or Iron Tower.
I guess I'm just not cool enough to do these dungeons? Maybe because I'm not in a big guild? Maybe these places are designed for a smaller percentage of the population? I don't know.
I do know that I'm bored. I know that with certainty.
