E/Mo Knockdown build need feedback + suggestions

I wanted to make a pure knockdown build, mainly because it cancels whatever your enemy is doing, and causes them to lie on the floor for the tanks to get a couple of extra hits in.

This is what I have come up with so far...

1. Gale - Air magic
Energy cost: 5
Recharge time: 5
Casting time: 1

2. Whrilwind - Air magic
Energy cost: 10
Recharge time: 30
Casting time: 3/4

3. Signet of judgement (elite) - smithing players
Energy cost: N/A
Recharge time: 30
casting time: 2

4. Bane Signet - smithing
Energy cost: N/A
Recharge time: 30
casting time: 2

5. Meteor - fire magic
Energy cost: 10
recharge time: 30
casting time: 3

6. Immolate - fire magic
energy cost: 10
recharge time: 5
casting time: 1

7. Healing breeze - healing
energy cost: 10
recharge time: 2
casting time: 1

8. Balt. Spirt - smithing
energy cost: 10
recharge time: N/A
casting time: 2
-1 energy regen

Pros +
1. Able to knockdown one or mult targets.
2. Able to still cause some major damage to one or mult targets.
3. Able to heal oneself.
4. All spells cost less then 3 seconds to cast.
5. All spells cost less then 10 energy.
6. Gains energy while taking damage.

Cons -
1. Way too many att to put points into. (4)
2. Exhaustion
3. Recharge time a little high
4. Can't res other players

I have tested it in pvp it works pretty good, however I would like some feedback and suggestions to make this build a little better.

Before I had glyph of sacrifice + meteor shower, but a 3rd exhaustion spell and high energy cost didn't work too well.

Points
Air magic: 4 (+ minor rune)
Fire magic: 12 (+ flame's eye and major rune)
Energy storage: 9 (+ sup rune)
Smithing: 7
Healing: 5

Any suggestions + feedback is welcomed, thanks.
