The Lost City of Ampdapor. "Idiot! Halfwit!"

Honestly though, the magic/physical defense ratio seems like a unneeded archaic design at this point of the game. Example from WoW, most people had enough defense (or HP) that they'd take relatively the same amount of damage from unavoidable AoEs, either that or it was static damage reduced only by resistance. It was actually on the tank's (as well as warriors) that'd have a miserable magic defense, but they had enough hp to take magic hits.
