Heroes 6 - Discussion

As a rule, Necromancers prolong attacks for many hours, perfectly knowing that this is one of their main advantages. After all, their troops never get tired.

It reminded me of one feature from King's Bounty. There, after 10 rounds, Rage accumulated twice as slowly, and after 20, it stopped accumulating altogether. It was explained that "your troops are tired and no longer want to fight." I think a similar feature would be appropriate in Heroes of Might and Magic.
