Specifically for R55Max:
Doesn't the Moon, which breaks the game with units having only 1 attack on the first week, bother you? Doesn't Grindan, who often gets a large amount of mana on turn 111, bother you? Does a level 5 Izra/Vidomina from the Dungeon (whose chance of finding is simply minimal) scare you, but not Galtran, which can be used without any restrictions for almost any castle? Come to your senses.
Regarding specialists at level 4. I definitely believe that they should be unbanned on all standard templates of level L and higher. On level M templates, they should be banned. Believe me, mass slow and mass haste are much scarier than this meteor shower. And Solmyr himself is a rather weak hero: his stats are poor, and almost all points go into intelligence, and he is countered by tactics easily, just like the meteor shower units.
Why doesn't it bother you that the game is called Heroes of Might and Magic, but we only have the sword? Aren't the sphere and the cloak of repentance enough for you? I personally feel bad for the mages.
