IF you played BLM as a thunder mage in XI, you played poorly and wrong. There are many isntances lightning based spells did no good, and you need to know your element tree, how to cast one element first to lower the mobs resistance to the next, to increase damage. There are many times Fire was stronger, and others where wind based were.

WHM is light based, BLM is element based. IT isn't balanced right now. THey awknowledged that, and hopefully will address it. BLM are pure DD, as as such, need the ability to control high damage, and elements against specific mobs (since that is being introduced again).

WHM shouldn't be acting like a scholar class. Even tho a weak form. IT should have light based, with a couple potent light based spells tossed in.
