Heroes 6 - Discussion

I meant how the fifth game changed compared to the first four. Why is there nothing new!
The division of spells into sections, the ability for creatures to roam without a hero, the participation of heroes in battles, and the emergence of at least a primitive tactic: one unit after another, many creatures have abilities, etc.

Are you talking about the changes in the fourth game? In the fifth game, units no longer move without a hero, and the division into schools was already present in the third part. Heroes have been participating in battles since the fourth game; in the fifth game, their involvement in battles has been slightly limited. And in the third game, the hero could simply cast spells.
