Movement speed cap.
I think the movement speed cap at 50% is way low. Especially in the future where we will have beastman that are supposed to be fast.
Right now I can get to 50% with frenzy on even not on the roads which make roads not give higher speed.
People may say why would anyone want higher movement speed, well you need 50% speed bonus to catch deer with mele.
Also it helps a lot when gathering resources all around the map.
