Then its Templar's Might. I don't know anyone who would trade for an unided Tyrael's anyway. Cause even if the lvl is 99 on the item (meaning Baal Dropped it) it could still be Templar's Might and not Tyrael's. It's just now you know for sure without IDing it. If you don't plan on using it than I wouldn't ID it. Who knows. Some newb without maphack may cream his pants if you throw it in a trade window .
