thieves guild dlc info and classes

bossonova420

for the thieves guild dlc do you have to play as a nighblade? if not then how viable are the other classes with the thieves guild dlc?

Enslaved

Any class can do it, NB is simply cheaper to do it, since you don't need invisibility pots at all.
I done it on sDK without any problems but moderate bounties.

Done it with templar healer/dd and had no problems... just took some time.
