Here is a idea for a update. Bring in the Hexblade from D&D 3.5 in. The Hexblade is a close combat fighter with limited spellcasting ability, mostly using it to debuff or lower stats of his enemies. This ability is through "curses" or "hexes" and at higher levels gets a aura of unluck which gives enemies miss chances against him because they caught bad luck. Luck is a central theme in their backgroud. Supposely they are such unlucky people they had t learn how to make that bad luck affect their enemies instead of them. They lose the fighter feats for this limited ability but i think its a cool idea.
I would think this would wed nicely into current ddo animation abilities since it is not asking for much more in the way of animation besides normal casting rites or something, because most of the affects are invisable just affecting the luck of the enemy. balancing those hard fights.
