The /list isn't the real problem...

The real problem is SKs wearing plate.

Think about it:
Paladin = warrior (plate) + cleric (plate). Thus paladins can wear plate.
Ranger = warrior (plate) + druid (leather). Thus rangers can wear chain, which is in between plate and leather.
Shadow Knight = warrior (plate) + necro (cloth). Thus SKs should get chain at best or leather. I actually think leather makes the most sense to even out the number of classes in each tier. We'd had 4 plate, 3 chain, 3 leather, 4 cloth.

Devs, please fix this massive oversight.
