That unit was a bit controversial in the 'multiplayer lobby'.
I followed some passionated debates about that and played a lot of test games (team games or 1v1).
Here is a proposal about a slight nerf:
- making a more consistent run speed (so we are just below a cavalry unit)
- reducing the armor a bit (the current -3 is just removing the spearmen armor bonus, so -4 would be good for that naked unit).
