I two-shot a recruit Jedi Shadow yesterday with Shock+(1/2)Shock + Maul.
There was skill involved in that?
So you managed to get around either a 5k shock and a 9k maul (with a proc) or a 7k shock and a 7k maul(with a proc). Neither of those options sounds believable. So there isn't a lot of skill posting made up crap either.
Maybe if you were a carnage mara, you might get a gore+ravage for 10k then a force scream 4k+ but that's still not really 2 shotting.
