Honestly speaking, when playing unfair, I didn't even bother with the spells that require hitting. They practically never hit. In the case of WotR in the second act I practically stopped using any CCs, I decided that it makes no sense if you do not build a character specifically for what is possible and so only at the end of the act, and only because of a single mythic feat that clearly does not work as it should. Spells that always hit but deal less damage on a successful save are probably the only sensible way to deal damage while playing caster. Most of the time, magic is used to buff or summon skeletons (other summons are weak and not worth using).
That's very backwards considering how the design philosophy has always been that the real damage-dealing caster archetype is the sniper one, and the AoE stuff would eventually just run into lots of things having some form of evasion turning it all useless while high saves make the instakill-type spells a lottery. There not being at least an analogue of Isaac's Missile Storm in the Owlcat stuff is really annoying.
I guess that's also what turns kineticist very unreliable at later levels, because your BAB is garbage (as in, it's anything below a pure martial character's one) and you have very few ways to increase your accuracy since you don't attack with a weapon. You can't even fill your level 1 slots with True Strike to circumvent the insane AC at least somewhat unless you pick a few caster levels, dilluting your character progression.
