NHF – new heroes for Heroes V 3.1.

Could you leave Shagrat as is, but set a limit on the number of bonus attacks from the special ability, tied to the hero's level? For example, the initial limit could be 1 attack, and then it increases by 1 for every 2 levels. And do the same for the special abilities of Kubera and Freyr. I think this would make these abilities more balanced in the late game on large maps.
