I did 18/21 last time for 6 PS and max athletics. Its still alright on the shooty, but I kept saying fuck it and picking up whatever stupid masterwork I could find on the ground. I probably got more kills with flamberges that werent mine than any of my own melee weapons though, haha
I recommend playing the 18/24. thats the gen I finished in like 4-5 days, plus if you go past level 30 you can fill it in. Otherwise you're playing like cyranule (++) or burnt out shitty depressed uumdi (--).
Seriously as soon as I picked up the english bill again I got a raise at work, the lady I love came back to me, and I had several realizations about my self.
