Not how we do things. We don't force anyone to do anything, we ask and if they say no then your done and you find someone else. These dungeons are really meant to be done with a LS especially since it is considered the temporary end game content. That problem may rise up but you have an option, either do it or don't, noone is going to force you to do anything. Either you will allow it or find another group, end of story.
