^ Where in your order do you have tSSSSS? I would assume it goes after this one, but I want to make sure

It doesn't matter. On the download page, I suggest using this, Better Mage Armor, tSSSSS, Scaling Elemental Runes, and Conjuration and Summoning Fixes. None of those mods change the same files, so they can be loaded together in any order.
Maybe you should increase it for other schools too? I dunno, magic just seems really underpowered compared to physical weapons, and destruction and restoration are the only schools I really make use of as a melee-magic hybrid character.
I've been using this for a while now on a spellsword. Even without using dual casting at all (due to the sword taking up a hand), I've found magic to be quite useful now. I'm really loving being a badass who walks around in just pajamas using his mind to deflect damage while throwing lightning and swinging a sword. Oh, and screaming. Making enemies fly backward by screaming at them isn't always useful, but you've just got to do it anyway. http://tvtropes.org/pmwiki/pmwiki.php/Main/RuleOfCool and all. Anyway, I really think boosting magnitude or duration like I have already fixes a lot of the balancing problems. I might just think that because I also use tSSSSS, though, so my pajamas are like extra capacitors or something for my lightning bolts.
