I forgot to mention that I also found a lot of the name changes questionable. Impale instead of Icebrand is not a good change, even the vanilla Iceblast is better, same thing goes for a lot of other vanilla names (Spiritsurge, Gravity Flux, Dead Man's Ivy, Major Heal, Word of Pain). I don't think it was an issue of space in all cases, either (seems to be 20-24 chars), so it was probably something you wanted to change either way. Of course, we, the players, have to get used to the names either way, but that's not a valid reason for questionable name changes. Just being honest with you, of course. I admire your dedication to this mod and think most of your changes are great and make the game more enjoyable, but this was not one of those changes. I don't know what feedback you have gotten on these name changes, but at least consider this piece.
There are also icons for browse (exclamation mark) and learn (checkmark), which you can memorize if you really have a hard time telling the sections apart.
Really? I see no reason to use them as a speedy fighter class over ninja, other than stealing. Ninjas even have the same ranged options, or very close. Decreasing the TP of Sneak Attack to 20/30 would be a good enough buff, it's a little TP heavy to use constantly. Maybe add automatic weapon proc, too, if that is possible (or another separate proc).
They still wouldn't replace clerics fully, they don't have mother's blessing, major heal and a few other spells. Evacuate and exorcism just means that they could be used as adequate replacements for clerics. They don't have anything other than divine magic, correct? Even though a lot of elemental spells are listed as learnable they can't actually use them.
