It's not at all clear that spellcasting should provide greater and more effective options than non-spell options.
Actually, I think it is clear. There are problems in implementation but it is always the case that limited use abilities should be more effective than always-on abilities. Otherwise you lose obvious progression paths (more uses per day progresses to always on, for example) and create trap choices that are generally unattractive.
It's fairly well argued and almost certainly a Truth that between bonus spells, cheap consumables, item crafting, and a number of other things, casters don't really face an issue of limited use. As such, spells are almost certainly over-valued as a resource.
If every spell in Pathfinder had its casting time increased by one level (so a spell that is now a standard action takes a full round, and a spell with a one round casting time takes a minute), casters would still have overwhelming narrative power (I...
Most of your suggestions are only effective if you also remove the ability of casters to create and use easy consumables.
