Traps. Physical objects that can be created by a smith, carried around in your inventory, then placed before/during a battle to damage enemies and/or hamper their movement. All of the code infrastructure already exists, since there are already bear traps in the game - you just can't make them or place them yourself. Runes are an incredibly poor substitute; they require an obscene amount of magicka relative to the damage they do, don't last long enough to prepare for a serious battle, and don't significantly affect movement. It's the one feature I've seen in other games that I miss most in Skyrim.
