Mes build - does this work?

Mesmer / Monk

Fast Casting: 3 (6)
Domination Magic: 12 (97)
Inspiration Magic: 12 (97)
Skills:
1) Backfire - (15,3,20) For 10 seconds, whenever target foe casts a spell, that foe takes 119 damage.
2) Ether Feast - (5,2,8) Target foe loses 5 energy. You are healed 24 for each point of energy lost.
3) Energy Drain (elite) - (5,1,20) Steal 18 energy from target foe. This is an elite skill.
4) Energy Tap - (5,3,20) Steal 13 energy from target foe.
5) Power Leak - (10,1,20) If target foe is casting a spell, the spell is interrupted and target foe loses 22 energy.
6) Signet of Weariness - (0,1,30) Target foe and all nearby foes lose 9 energy.
7) Purge Signet - (0,3,30) Remove all hexes and conditions from target ally. You lose 10 energy for each hex and each condition removed.
8) Mantra of Inscriptions - (10,0,20) For 78 seconds, your signet rings recharge 45% faster. I don't see why it wouldn't as is, but we have primal echoes in our team. We also have quickening zephyr. Anyone see a better way to do an energy stealer/protector?
