What types of combat do fans of Heroes enjoy?

The point is, you can't protect yourself from everything, and you won't become an unstoppable killing machine.

I'll be satisfied if I consistently win in fair 1-on-1 battles.

Such training can take a lot of time, and spending it on that... well, it's not ideal. It's better to spend that time on Heroes of Might and Magic.

Well, it takes me about 4 hours a day, not including travel time. If you don't do anything other than training and studying, you'll have more or less an hour of free time. There might be some sleep problems, but show me someone who has both studies/work and a normal sleep schedule.
