As for the restructuring — IMHO in the classic HeroesWorld it is optimal. Because there is no reason to make obtaining the most important casts of the game, which are at level 1, too easy. Slow, View Earth, and View Air.
There are, of course, downsides. Necropolis will find it easier to get Animate Dead, but on most templates the start already uses Tanta, and on Jebus Cross it is already imbalanced. It will be easier to get Armageddon, Resurrection, and Town Portal, but I wouldn't say that is necessarily a bad thing.
