One of the mechanics I want added the most is the ability to switch to combat mode. Auto-sheathe is already a problem on its own, you can't feel in control of the character, which is immersion breaking. On top of that, even if auto-sheathing is disabled, you can't switch to combat mode, which means you can't block unless you get close to opponents. There have been many instances where I couldn't parry arrows because of this problem. So I thought of a possible solution for this:
New keyboard layout for high/low profile actions would serve this purpose decently:
1- When sword is drawn, right click *always* works as parry/block. If you want to use spidey senses, however, you can use shift + right click. Two birds with one stone.
2- There is another issue while in combat mode that you can't jump. Let's say that you are overwhelmed by enemies and want to climb a rock or jump through a collapsed bridge to run away. As usual, let us roll with spacebar, but when spacebar is held, let us jump. This, again, would be an efficient solution.
If you have any other examples, please feel free to add. I want to be in total control of my character, instead of being limited to certain set of moves.
