27 Dung as in 27 shit? Lol. Jk. I don't think 50 dungeoneering will be worth much man, if you get 50, someone else will have higher. Wouldn't get your hopes up.
I don't think an acc with just dungeoneering is worth much unless its really high level (70+). The skill isn't really that hard to train.
I guess you could get a few dollars off 50 dungeoneering, disregarding other stats.
