This at-will unaugmented seems to be pretty strong. Especially compared to Resolute Shield, www.wizards.com/dndinsider/compendium/po... which only gives resistance against the creature hit. Do you think it will be nerfed down in coming erratas?
Other things being equal, resistance against all attacks for a turn compared to an equal amount of temporary hit points usually favors the resist when you expect to be damaged 1+ times per turn, and the THP when the average is less (because of the chance of keeping the THP for next turn).
