the only thing i do not like about drains is that it will OE your weapon, which makes most profs useless in PvP. i can live with the hurt it my nano skills i just go to smaller heals and smaller init debuffes (BTW i am a doc) but the thing that hurts the most is the weapon OE, i think they should make it so Drains to not OE a person in PvP then it maybe a little more balanced. just a idea what do you traders think. you still have your drain but there is no OE for the people you are Draining.
just my 2 cents.
