E/W Knockdown based build

I tried making an Earth Elementalist/Hammer Warrior which is based on Knockdowns, I think it would be a strong build in PvP.

Aftershock
Description: Nearby enemies take 26+ damage. Knocked down characters suffer 10+ additional damage.

Armor of Earth
Description: You gain 24+ armor, but move 50%- slower than normal.

Ward Against Foes
Description: You create a Ward Against Foes at your current location.
For the next 8..20 seconds, enemies in this area move 50% slower. (Radius 39 feet.)

Earth Shaker [Elite]
Description: All adjacent foes are knocked down

Belly Smash
Description: If this attack strikes an opponent who is on the ground,
the resulting dust cloud will blind nearby foes.

Hammer Bash
Description: Knock your opponent to the ground.

Healing Signet

Resurection Signet

12 Earth Magic
8 Energy Storage
10 Hammer
5 spare points

If anyone have any insight on how to improve this or if I should simply skip the idea, please let me know

Use W/E, lose armor of earth, get 12 hammer and 10 earth and 8 strength.

you know thats what EVERYONE says now?

E/W has WAY more energy than warriors puny 20, allows him to cast more spells over and over, so dont just rush and say "DO W/* ITS BETTER!!!!!!!"

E/W = More energy, less armor

W/E = less energy, more armor
