I would like to know if its possible and suggest to add some neutral units, like a camp with some hero lvl 15 with massive heigh. Its boring always same units in neutrals, maybe randomize camps!
I've made an altered melee map where heroes can level up to 20. Their abilities have all got 6 levels (and their level 6 abilities 2). I've got one little problem, though. For example, a level 7 Blood mage can already pick level 4 flame strike, instead of having to start levelling...
