Your spell fixes:
Alternate form: I'd still suggest limiting at least movement modes. This one is still about 6 spells in one. I thin kthere were ways of getting flying and swimming forms. I'm also still lobbying for ability modifiers over ability scores.
Astral Projection: if you are in no way protected, what exactly is the point of it?
Mage's Disjunction: i'd still like the option of taking apart a magical item. Perhaps as a secondary function at touch range, on a single item? Or should that better be a different spell.
Wind Wall: mentoin that it the penalty is a wind effect, as there are ways to ignore those.
