Another advantage of Haven over Chaos is quick access to tactics, which provides additional army reinforcement.

Well, actually, Chaos also has quick access to tactics))) with the exception that Haven has two heroes to choose from: one of life and one of death... while Chaos only has one of death... but in principle, the difference is insignificant...

As for the confrontation between these two factions, I'll say that both are good in their own way... and you can win with either faction... Haven has very insidious magic, while Chaos has very destructive magic))) Haven has Titans, which effectively resist Chaos, but Chaos has Black Dragons, which resist everything :-D in general, everything is relative...))) the main thing is to correctly and effectively use the advantages of one faction and the disadvantages of the other to achieve victory)))
