Pro tip: There is a difficulty option to remove the inflated stats of the monsters in the game, keeping the other difficulty options, something that makes the "bloat gets ridiculous" a moot point.
nevertheless, as said above, kineticists, alchemists and many spells target touch AC, you can pick mythic feats to ignore energy resistances, using the two companions or the classes with ac debuffs, like hexes or slayer/rogue combat skills, and pilling buffs and resistances usually makes your job easier. Do not be afraid to use scrolls, potions or wands for particular combat situations ( death guard, stoneskin, delay poison, protection from energy/evil, remove paralysis, restoration, etc) You even have Nenio, that is a specialist making scrolls that you can even use at camp even if it´s not in your party.
