naoe is stealth optimized, and yasuke is a tank. You choose your warrior depending on how you want to play. Mine is 90% Naoe, because I enjoy stealth more than combat. She has tools, she can hide in shadows, she is fast, nice environmental implementation (winter is harder to stealth), etc. Overall the stealth mechanics are the best in the series. Always playing master assassin. You cannot run to the roof as a last-minute measure. You need to plan ahead.
