I thought about it and ultimately changed my mind. Dave was right; the problem isn't so much with the game master as it is with these spells that need to be fixed.
Fixing the game master will lead to a very monotonous and boring game. We need fixes like diplomacy, which may be needed in some cases. Also, skills, hero selection, and building should differ depending on the draft, ideally. Therefore, we need to fix these spells, not make them easier to obtain.
Regarding the university, I don't even know. On the one hand, Dirty's idea is interesting, but it will add randomness, which could be quite critical. For example, players are playing a mirror match, the map is suitable for oil, one player gets earth, and the other builds a university hoping for earth, but it's not there, and as a result, they fall far behind.
The idea of different spell costs seems more interesting; ideally, we should collect statistics on the purchase of elements at the beginning and use the statistics to create interesting diversity.
