Edit: Read laser instead of Taser /doh.
Ion Pulse is what you mean by Taser?
Shield Specialist is the least dependant on Ion Pulse (though at first it's the only skill to trigger the 5% damage reduction) but you still use it (on single targets especially.)
yes, ion pulse and pulse cannon, those things that make me think im throwing sith or force lightning, or some kind of ranged taser
shield spec? going through it myself seems pretty weak, can someone link me to a guide on how it synergizes and all
so i can understand how it works?
