But, you'll find 'not dying' much easier and faster to learn than 'winning'. If he got to you and attacked you, without you noticing him, you didn't use where enough. Also, avoid Galadon and if you see said LFGBS on where while ranking, assume he's going to try to come over to you and kill you and take evasive maneuvers.

Its an old wise addage to not stick around for a fight you didn't start.

As far as not RP'ing after a kill, my marans typically would say something to you...my scions might choose to gloat...my tribunals would say something about the law...but aside from those, typically I don't say anything after I kill someone. Its not bad RP to not chat it up with your victims and that isn't anything that has ever been punished. Not every character is diplomatic and vocal. And more often, they simply assume you know why you got killed.
