I finished leveling Warrior! After approximately 15 deaths, I was able to reach level 18 and put Warrior behind me. Thank god.
And I went and leveled Ninja too! It's up to 27 already and I didn't even use a stack of Shihei doing it. So that's cool. Now the question is do I level thief to 55 and do Genkai 2 (and some AF stuff), or do I just get Ninja to 37 so I can concentrate on one thing at a time?
I'm just pretty happy with my progress lately.
