Thats -your- problem, not theirs. While the gear you mentioned may not be ideal for an quick AK run, it's still doable. If you can't deal with it, then you're far too righteously minded.
I have gone into several AKs as the highest geared dps in the group, several times with another dps, or healer, or even tank who arent what I would consider 'great' geared. Do I leave? Nope. Do I give them crap for not being able to afford top tier gear, or having already spent thousands of tomes for DL? Nope again. I suck it up and do my job.
And I have never, once, failed on a run because of it. Yes, there have been times when the wall has taken 2-3 times until people get the hang of it. At times, the reason these people are badly geared is because they haven't ran the dungeon yet to have the opportunity to get the higher tier gear out of their own AF.
And yes, on more than one occasion I've had to single man the wall till its down because others die/fall.
Get over yourself. And anyone else on this thread/forum who think they are God's gift to this game.
