I've long since gotten used to the suffering in my maps. If necessary, there are always easier difficulty levels available. You could call hardcore a kind of trademark of my work, but... in my opinion, there are plenty of even more difficult maps on the forum.
I have no doubt that there are very difficult maps on the forum. But what kind of difficulty do they offer? I can also greatly increase the number of troops and enemy stats, and somehow win through incredible luck with loading screens, and say that "my map can be completed on Hero difficulty, and if you can't do it... it's just that I like hardcore, so suffer." But will players be happy to play such a map?
