- What are the drawbacks of Heroes 3? (What didn't you like about it?)

1. No one argues with that; it's true. I've been saying this from the beginning.
2. You yourself claim that "I said so."

So, I don't understand what you wanted to say at all.
I completely agree that I play Heroes 5 much better than Heroes 3.
But you could express your thought a little more clearly so that we could continue the discussion!

I'll try to be clearer: in online battles in Heroes 3 between strong players, the outcome is determined precisely by the ability to play with units of the initial levels; it doesn't happen very often that the game reaches Archangels, although you also need to know how to control them. Although, there's nothing wrong with the fact that if you manage to develop to that point, the game becomes easier, of course; I don't see this as a punishment for the difficulties in building them. As for buying additional heroes for more money, there's little point in it; it's unlikely to make the game more interesting, it might only slightly (and I mean slightly) level the playing field between novice and experienced players online.
