So you were the one in the KQ by your self XD. I noticed that there was a pirate one with one person in it. I was about to take a screen shot and say OWNED but I guess you just did it for fun.

Yeah, that quest is basically impossible. I was in a good group with most people 24-25 and we still couldn't do it. Everyone needs to be high lvl buffed before entering, then you might be able to do it.

I was able to tank the Bosses with scrolls and heals fairly easily at level 22.

It's quite easy as long as you have enough tanks and healers. If the boss gets away from the tank then most of your group will die very fast. There is also a problem with certain people who don't listen and purposely pull in mobs from out of nowhere and screws things up. You need to tell everyone from the start not to stray from the group and to try and avoid as many mobs as they can.
