Personally, lately I only want to play Heroes in Tournaments. Just playing against the computer is getting boring; I need some motivation.
When you play a Tournament map, you try to maximize your skills in this game. Otherwise, on the same map, you would play more slowly – but for your own enjoyment (but in a Tournament, sometimes you can't be distracted by minor things with your main hero and have to go towards the final goal, replaying battles, and changing the logistics of movement...). But then, when you compare your Walkthrough with those who showed better results, you adopt all the best things that your opponents used, learn something new in tactics and strategy, and then next time you will play even better.
The only thing that's a pity is that the internet at work is not good, so I can't try playing online.
You need to play in Tournaments anyway, especially since the duration of any Tournament is very long – 1 month.
I just registered on a portal, participated in the very first Tournament, and got 1st place. The only bad thing is that 35 people registered, but in the end, only 10 people were counted. More than 20 players are in the negative. And the victory is all the more significant the more strong players competed with you.
In general, it seems to me that it would be possible to hold more Tournaments in a year, but reduce the duration of each Tournament. And it would be good if Tournaments for Heroes 2, 3, 4, and 5 did not overlap in terms of timing.
