This is really fantastic news, I can't wait for it, here is what I would like to see:
-more class specialization abilities and branches, both for magic and might, like summoning, destruction, debuff, 2 spells per turn but like in Armored Princess so it is balanced, new awesome synergetic might abilities and so on
-no new races, really 5 races is more than enough, but upgrade races with new units(1 per race) but please
NO MORE FEMALE UNITS ANYWHERE(you really went overboard with that one
)!
-sharpen the shadows and make them so they don't overlap with edges, this is the only thing that visually needs to be fixed
-fix this
HUGE BUG
-add champion neutral creatures, which would work in conjunction with each race, but once again, no female creatures
-keep hiring Puppet Studio, they make the best animations!
-
ability for each hero to get a different mount(other than horse), which would grant special attributes
-better looking cities, Haven cities especially look extremely basic
