A 4 out of 10?? Haha, how can it even resemble a 4? Or rather, how can it be better?
There are no upgrades, and the battles aren't faster than in Heroes 3.
So...
Perhaps it was meant to refer to alternative upgrades...
Regarding the speed, nothing has been said about that yet....
In general, not much time is left... Heroes will be released at the end of September, and we will all enjoy them. If we don't like it, we'll play Hammers of Fate...
So, let's not panic... It's still too early :D :D :D
