The Samurai of war time would have attacked from behind, the Samurai of propaganda may have said they wouldn't. Though I suppose people like the one of propaganda otherwise they'd ask for a spear or a bow (which Samurai excelled at) vs a sword which was their secondary (practiced more later, but not because of being suddenly superior).
Thats probably another part of why I want to see Samurai DD, just to reduce the amount of serious exaggeration - indestructible super perfect sword soldier (Katana was completely capable of cutting though

). Poor western knights don't get that amount of love, in fact they get anti love... lol (at least it seems to me a lot of people assume they were a bunch of dumb brutes and dumb blacksmith, both far from the truth).
Its true that it is not really important to dispel anymore, not like we're facing a cult of Samurai trying to take over the world - but I've never been a big fan of any sort of self-gain exaggeration especially one that tends to be nationalistic. I've always wondered if that is why SE frequently gives Samurai coin toss as an ability, to while keep some elements of fun romanticized Samurai but also to just say "hehe, most damaging attack depends on how much money you have" a make fun of the later period of an average Samurai.
