Most of the characters in my party have ACs near or above 20. They are nearly impossible for rank-and-file monsters to hit.
My solution: Throw lots of rank-and-file monsters at them, and moan ostentatiously about their stupidly high ACs when the monsters can't lay a finger on them. They get to enjoy feeling like they're beating the DM, and I get to enjoy the sudden terror on their faces when they encounter a spellcaster or a monster with a high attack bonus and lots of DPR... which happens fairly frequently.
