I just wanted to discuss about skill that you think shouldn't be elite.
Myself, I think that the air skill Lightning surge really is worth it as an elite skill. Indeed, not only do it cost exhaustion, take 3 sec to do the damage but it also do not have the standard 25% air spell armor penetration. The knock down make it a nice skill but I really don't think it's worth the elite tag. Here's the comparaison between lightning surge and lightning orb.
Lightning surge
Description: After 3 seconds, target foe is knocked down and struck for 14-83 lightning damage. This spell causes exhaustion.
Energy Cost: 10
Casting Time: 2 seconds
Recharge Time: 10 seconds
Skill Type: Hex
Linked Attribute: Air Magic
Lightning orb
Description: Lightning Orb flies towards target foe and strikes for 10-82 lightning damage if it hits. This spell has 25% armor penetration.
Energy Cost: 15
Casting Time: 2 seconds
Recharge Time: 5 seconds
Skill Type: Spell
Linked Attribute: Air Magic
As you can see, their damage is pretty similar BUT, lightning orb have armor penetration, a shorter recast time, do not exhaust, act instantly, cannot be removed and is not an elite. On the other side, lightning surge cost 5 mana less, do not need a line of sight(which is rarely a problem anyway) and cause knockdown.
All in all, I think that both lightning surge and lightning orb are about as useful, one is an elite and another is not.
