I am odd one out... to me I would say Lightning... reasons:
1. 5 ees for holding storage for shrining
2. less mana used to cast it
3. it deals more higher damage overall
4. you may want to increase your Lightning profs [I would, not sure if you want too]
5. Other reasons like casting on HH when you pass [this is if you do not have the Melee dmg output compared to the Casting dmg output of items you have collected]
... So ... I am the 1 vote for your lightning... and yes wind is really compatible... but then... I am unique...
