This spec is made to max the dps using the cannon, to have the max amount of stun and to slow mobs (using the Immobilization Copter).
As you can notice, i didn't select the spider mines, i prefer the shock granade beacause the stun duration is three times as long, and it has also the 100% interrupt chance.
Using Coup de Grace, it is really usefull to have stunned enemies, and if you spend most of your stat points in Strenght (as i do), Coup de Grace will be a real blast!
Forcefield is the main spell to consume the charges, and if maxed it is quiet usefull in party. With one point in Charge Reconstitution it will also make you gain life before shielding you.
I am using this spec in elite mode, and i really have no problems at all 'till now.
Sorry for my english (it's not my language). Please tell me what you think about my spec!
