What is your opinion about Heroes IV?

Only when you have a lot of spells and have something to choose from, you realize that most of them are unnecessary, and you use the spells that are more effective. In this sense, there are a lot of unnecessary spells in the 4th installment. But, of course, this is just my opinion.:)

This is actually a huge plus of the 4th installment. Because it allows you to play with spells. The opponent will never know exactly which spell I will cast.
A simple question: which slow is better? Mass slow or not? There is no definitive answer. It all depends on the situation and the vision of the battle.
