In Firestorm's case, his weakness was probably imposed to prevent the implications of his powers being used on living people and animals. Since Blackest Night eventually provided us with a very memorable example of just how scary his powers could actually be, maybe it was for the best that writers watered him down early on.
Commentators both in-universe and out have pointed out that Firestorm's real weakness is being an idiot. He can simply turn the air around someone to steel, yet his infamously lame villains have included a powerless albino dwarf and a guy with a rope.
