Sorry, I know this is a couple pages back (I'm just getting caught up), but this jumped out at me a bit for a couple reasons:
•Would the Barbarian in question have survived without the DR from Rage? If not, that means no one else would have either, regardless of their "tanking" capability (such as a Fighter or Paladin or such).
•
Everyone always seems to forget that part of Cunning Action is the ability to bonus action Dodge. I'd think a Moderately Armored Rogue who can Dodge every round without giving up their offense is in a better tanking position than their more traditional tanking contemporaries.
Edit: Well... dang. One day I'll learn not to post in the middle of the night while tired. Not today though.
Thanks for the catch, Kane0.
