First sidenote: could also work with mouse and keyboard, for the pc fans.

The idea is a new way to enter hidden stance as a Nobushi, as keeping the right analoge stick down messes with your mix-ups.

"Dodge backwards + holding heavy attack"
You will stay in hidden stance as long as you keep heavy attack pressed.
This will open up the full movement of the right analoge stick, as well as gives you full options over dodge and kick (from hidden stance).
As your basic mix-ups are light attacks keeping heavy occupied wont cause many problems.

Hoping for some support for this idea!
