yes, I can post a walk through,
I soloed it with assasin/fighter, the start is a pain in the arse!!!! there are two critical points about solo assasin/fighter
first is the beginning, second is once you dual to fighter
in the beginning i specialized in:
long sword +
cross bow +
single weapon style +
when I dualed (lvl 10, it took a while to reach that high), I specialize in the weapon i desire to use: scimitar.
the trick is, DO NOT get the exp of any quest until you dual to fighter. say, if you freed Copper Corrant, DON'T talk to the owner until you dualed to fighter. this way, you gain exp for your fighter to pass the initial low levels
my fighter started from level seven by doing this (and this is not even an exploiting bug)
