This post is not quite up to date, but I'll take it up. It's not about the lateral movements or softer ones, but it comes close and I would like to open a new post.
Since I play FH2, I have the following problem.
Of course I tried to put the function on different keys.
But since then, I have problems with my left little finger: D He becomes deaf and I get problems with the finger and the hand while playing.
It would be great if you did not have to keep pressing the sprint button all the time, maybe it is possible with the engine to give the player the option to press the button as needed. Or that would be my wish that you only have to press it once more and the character sprints until another movement is taken or he is exhausted.
It may not be a problem for many, but I noticed that because I play mainly as an infantrist and you have to walk properly with the big cards. Which I think is good.
Perhaps one could give the player in the future the freedom of choice as he would like to play, if this is technically possible.
