Both Dark Knight and Paladin are spellcasting tanks.

Though I'm sure everyone would love to see a mace character and a time mage to show up, I'm not sure they fit into tanks (the time mage that is). Also stop/disable would either be a crazy stupid overpowered or utterly useless. Think about it. If you could stop/disable a boss from doing mechanics, thus pushing back the enrage timer or skipping mechanics... A bit overpowered... And if bosses aren't effected by it... Useless. Though I admit that I've not played 12... So if you could elaborate on how other abilities would fit, that'd be great!

From what I do know, I'd also really like to see Time Mage show up in the game... And a mace user as in any of DPS/tank/healer would be awesome.
