i don't need a jump, wasting a button on that... no thanks.
But i DO get annoyed when i have to walk around abjects that look low enough to be jumped over.
There simply should be a auto-jump feature that would take effect within a certain height tolerance.
Example: when walking against a low fence your character would automatically perform a jump and you would cross the obstacle without a slowdown.
This could be completely automated and adjusted with various parameters so you would not be able to auto-jump where you are not supposed to just as you can not walk where you are not supposed to.
