Some may feel differently, but I'm not happy with encounters like on 122; after all, there should be at least 2-3 weeks of peaceful development, but if someone is so powerful that they break through the ГО by the 2nd week, then it's clear they have a better chance of winning.

Study the template scheme carefully. The path to the opponent is usually available via general secondary resources!
And breaking through the ГО in the second week is very realistic. It all depends on the ГО.
For example: I played against Wicc. He broke through the ГО on 122 and took my Castle. And the ГО were crystal dragons, which fell to the deadly gaze of mighty gorgons. Sometimes the ГО consists of some slow monsters like hydras, who are killed by a slightly leveled-up hero after mass-slow, archers, or angels—of which you can scrape together about 7 by the 2nd week. I won't even mention Galtran and Shakti, who take Dragon Utopia in the 2nd week...
As for Solmir, if he finds some knowledge artifact and gets a couple of level-ups, he can be a serious threat. He'll attack with seven fast units and will definitely last two rounds, and two chain lightnings can seriously batter an army...
