As we know some weapons like staff dont allow the heroe to have a mount, devs has told us this can´t be fix cause require new animations and other stuff.
My idea is for balance, cause now those heroes feel inferior to the ones who can get mounts, what i propose is that if you equipt a mount, you can´t equipt a shoes item and vice versa.
In this way heroes who are unable to have mount cause their weapon will not feel inferior to those with mounts cause they can have shoes while the ones mounted cant and also it will make that those heroes who can have a mount are not forced to have it by thinking if not they are losing power cause now theres gonna be a trade off use mount or use shoes.
This will help not only balance but also roleplaying cause if you feel your heroe should not have a mount, with this change you will not feel you are losing power by not equiping the mount cause you will have shoes.
