Regarding the statements. Have you even played 4? Not just for the sake of it, but with a strategy?
An army without a hero is only useful for delivering reinforcements and simplifying the clearing of creepers that appear every month. In battle, it's unusable. Because the Battle Database practically doesn't work. There is no luck. Just a large squad of creepers.
I was expecting something very similar but with changes and new possibilities, instead I got a fundamentally new game; yes, of course I agree with you, an army without a hero is very convenient! At first, I absolutely loved it!, but then I played as you say, with strategy, and I immediately felt like hugging my "white friend" :D (joke)
No, in reality, I cannot accept such changes, I just can't, and that's that...
I don't know about you, but I didn't use many of the spells; I can't list them now because I don't have the game and played it a very long time ago, and I'm afraid I'll confuse them with the third one.
