Left Trigger to Dodge and Customizable Controls

I have a gripe that I need to let out. This gripe is with the developers of hack n slash games. Actually, I have another gripe that just came to mind, which I will get to in a few minutes. The second gripe is with ALL developers. Let's get to the first one.

Gripe Number One

Hack n Slash developers, let me point something out to you: Ninja Gaiden (Xbox) was released in 2004. Almost six years ago to the day. And yet, almost none of you seemed to have received the very simple message: The right stick is not for dodging. Map that shit to the left stick! It's really easy: Left trigger is block, and the left stick is dodge. Simple, no? Here's why it's way better this way:

Speed

Think about it:

I'm in the middle of a combo. It's a four hit combo and I am just inputting the command for the fourth hit when I see one of my enemies initiate an attack. What do I do? I dodge, of course (or parry if that mechanic is built into the game) (and yes, you could also utilize a move with frame advantage and offset their attack (depending on the game) but shut up and bear with me here lol). So, where are my fingers at the moment I want to initiate the dodge? One is on the left stick, the other is on a face button, inputting the combo command. So, if the dodge command is mapped to the left stick, I can immediately dodge as soon as I see the enemy begin their attack animation, with absolutely no delay, correct?
