Got through the tutorial. I tried this a long time ago but I feel like I have more of an understanding concerning the basic mechanics now.
In actual combat I think holding down the mouse-button to change your setup could benefit from this either slowing down or "freezing" the game.
Well... this is an early comment but I I probably still have not figured it out. See that as either a detriment towards the tutorial or me as a player. Will play more tomorrow. I want to get how this works.
