SCH concept changes

[WaxSw]

I feel that a lot of these changes are misguided, they have problems as removing even more depth (ED), competition with existing tools without implementation of ways to make them coexist (Selene's kit which is basically Eos's but way worse, 120s of Recitation when Indom and Excog are 30s and 45s, Fey union...) or simply reward bad gameplay (Exploitation gives more returns the less mitigation there is when Sch and the party want to mitigate) without significantly changing the way Sch gameplay is, basically the 1 button spam, which is one of the main problems of the job
