I don't quite understand your points so hopefully I'm not wrong with my rebuttal.

One example of out of the ordinary tactics does not change the general view of what is essentially a warrior. Samurais are by virtue essentially japanese equivalent of knights. Armoured to be protected from arrows and other light weaponry and wield swords to cut peasants.

Samurai are what you would expect of your standard footmen in a millitary. They're not specialized assassins or anything like that. They're borne fighters that engage in open combat, head on with enemies. Your footmen, your soldiers, your knights.

My points were not in any means in respect to balance. They're purely aesthetical. And if a person won't play a class because of some misconceived notion that X doesn't fit in X role because of biased X reason never really was X class to begin with.

You're not a Knight if all you do is hide in the shadows and poison your enemies while they have their guard down.
