REWORK for the Academy. Is it needed or not?

What made you laugh so much?

When there are no normal arguments, completely unexpected absurd moves appear — one is afraid that morale will be taken away later, and you've fabricated a problem where it fundamentally cannot exist. Media answered your question extremely clearly, there's no point in repeating. I'll only add that, again, in HotA this point was never a subject of debate due to its insignificance.
And try re-building level 4-5 spells. Often the tower for Town Portal had to be built 4-5 times, and for Dimension Door it could go up to 7 times. It ends up being quite resource-intensive.
And as a rule, in the endgame, it's not specifically Slow/Bless/Blind that decides, but the presence of mass magic for them.
The only thing that re-building levels 1-2 can affect is Jebus Cross. It will become even more mindless. I'll steal the answer on how to get out of this situation from your sandbox — don't play it!:D
