it does kinda suck, and I would not strongly object to making them "any non-lawful" however I have no strong objection to unrestricted... I do see 15 Paladin 5 Warlock (or 14/6 depending on how things shake out) deathknights becoming popular. Not seeing much of anything interesting with Monk though. So I'm not sure we need to explicitly rule out Lawful...
So all hail the Knights of Cthulhu! Damaging bane aura and Dual wielded Spinal Taps*? Yes please.
*well one spinal tap the other a ToEE weapon for the 20% set bonus glamored of course
