Feather Fall being accessible through Air Elemental is not a very practical solution, because that completely removes any ability to use it outside of combat. It also forces you into using an Air Elemental.
You have misguided yourself. Number of skills in game is not limited by skill slots per level.
If by that, you mean you want to keep the same number of skills but REDUCE the skill slots, then I agree with that EVEN LESS. It will cripple diversity and cripple character builds, forcing them to only use the single most useful skills because they can't afford anything else thanks to a ridiculously arbitrary restriction. It will make for very boring gameplay, 1000% guaranteed.
If that's your idea of accessibility, then down with accessibility.
