I always thought Rapture should work with more than just cures and lolDivine. Has anyone ever used it to boost the Dia dot? Not I. Anyway, enhance regen potency, stoneskin potency, etc. It wouldn't be a horrible way to enhance storm spells I guess. I'd still prefer a new JA to do this though, so we could effectively boost weather for 2-3 people depending on the recast. If it were tied to our already stretched strategem count I'm afraid I might never use it for boosting storms.
