Knight of Cygnus: Soul Master

Getting 21 soul blade is a lot more important than mastery.

I don't really get that. The biggest flaw in warriors up until 35-36 is their low hits. Slast Blast is perfectly acceptable as a mob attack, it's what every other warrior class uses all the way up to their 70s and what Crusaders and White Knights use all the way up to their 120s. Lack of mastery prevents you from training as efficiently due to the chance that it may take you 5+ hits to kill whatever you're training on when you're unlucky enough to get low hits. The only reason I think Soul Runner is more important than mastery first is due to the improved movement it allows you. And movement is the only thing I'd sacrifice Mastery for that early in 2nd job. Being able to get to monsters faster makes it worthwhile, but the low hits are one of the first things I want to get rid of. I may yet sacrifice one or two points in Soul Runner to get Mastery even earlier. Won't know for sure until I'm actually playing as it though.
