The most challenging maps for you.

Good job. I'm reading that Fortress is still considered the weakest faction in Heroes 3... What do you think?

Everyone is wrong; that's what people who play it a little worse say. I would never say that Fortress is weak. Because with Fortress, there will be even more advantages (scouting and Castle). Fortress itself is a specific town that you need to know how to manage (a newbie will immediately fail). At the beginning, it's easy to play with, and most often, people use Fortress to attack utopias (not without the help of Gorgons and Viv). They also have a lot of meat (like Gnolls and Flies, which are the best for level 1 units). Their heroes are strong; the strongest "Fortress" heroes are: Thazar, Bron, Andra, and Stig. War can also be good, but if navigation is needed. Overall, I won't go into detail, because I'll get a lot of negative feedback because of my opinion.:)
