I've been watching someone play Sekiro, and I can indeed attest to the fact that relying on dodging will not help you much in this game. He died, like, 16 times to an optional mini boss that he didn't even realize he didn't need to fight. He also didn't realize he could use a stealth blow on this general, and instead approached him head on before each and every encounter (something the commenters were lamenting XD).

It can be kind of annoying when someone doesn't take the time to learn to play properly, but I guess that's the nature of the beast with YouTubers.

The game is fucking gorgeous besides all that.
