Hero can, as in 3, cast its spell or make its attack at any time during the round.
The last bit is good. The fact that heroes were subject to different spots in the initiative-bar was quite imbalanced in #5, especially in the Duel Mode which was otherwise quite decent.
that's the one and only incline over 5...
tbh, it looks more like alpha - lots of balancing and tweaking needs to be made
the system is good (like you could break it) - they added magic defense, initiative is in, some skills can boost it, but here's the problem - you need ridiculous amounts of exp to get them
two single player maps i finished with 7lvl despite crushing everything possible - that's 6 skills - imagine that in h3...
and spells are skills too, so...
there's a fuckton of artifacts but pretty shitty ones, and now the game badly needs loads of scrolls - which is nice, but if they leave like 3 on a map...
the game looks salvageable but they need to do a lot still
what is beyond repair is city development, and you can't forgive them the city screen - it just proves they had no idea about heroes
"unique" buildings? what a pile of shit, some useless ones in h3 were much more useful...
the maps look nice - lots of nice details - need better textures though
all in all, worth torrenting (provided you don't expect anything close to 3), but it will need a good map generator with lots of customisation options or you're left to play with user-made xxxxxxls with lots of stuff in them, atm mediums are simply unplayable
