i just started playing last month. my highest char is only lvl 38 =[

are you saying that if i mess up this char i can fix her later at lvl 65+ ? how much lant would that cost me?

skill reset, alot

They are both awesome. But a Rogue/Assassin does not need both. One or the other will do just fine.

A LOT of melee Rogue/Sins forgo Retreat and simply take Forward Dash, and they get along just fine. The extra skills and DNA can go to something else.

in battlefields u need both for a decent escape, especialy from rangers

i tend to run twoards people rather then from people. is this build suited for that style?

vengance do you like the joint strike skill?

Joint Strike is useful for stopping a would-be runner since it has a 100% chance of success, but I wouldn't give it more than 1 point. Soccor Kick and Home Thrust do the job better.
