Innate Doublehand for Samurais. This is driving me crazy. I've been thinking about this for a while today and can't figure out why the developers didn't do it themselves. Compared to Ninjas, Samurais get the shaft. They are slower, have worse movement, worse gear options and worse ability options if you want to Doublehand because you have to give up attack boost/safeguard/poach/whatever. Lets not forget the glaring fact that its a PA based class with a MA based skillset. Ugh. Granted, its a pretty good skillset. Plus Katanas run off of Brave which can no longer be raised, right? It just seems like Samurais have too much going against them NOT to give them an innate Doublehand. Besides, have you EVER used Doublehand?
Unless you've made some extensive changes to end-game heavy armor, their skillset damage formulas or their multipliers/growth rates, I can't see the justification for not giving it to them. Maybe you've made changes to them I don't know about but I feel they are lackluster, more so with Iaido affecting teammates.
Off the top of my head, the only other problem with a skill that I have is with Nameless Dance. The list of debuffs this skill has a chance of applying to an enemy is depressingly short. It really turned me off of using the class completely but, lets be honest, its not a very good skillset anyway.
