Well, you still have Arcane Magic....
But one thing I found, there can be some quicker ways to get the mats you need other than just farming the primals. Try doing this; Run the daily quests (I tend to skip the heroic one, I'm just impatient and finding a good group is a pain), and just use that money to either A) Buy the Spellcloth or B) Buy the Mats. This way, you just have to grind your primal fires and manas once every four days to get it, which shouldn't take too long.
On top of that, it might be possible to find someone that's in your guild to work out an exchange of services. Perhaps someone needs Primal Airs, well, you can get those no problem, and he has no problem doing Primal Fire. There you go.
You can also just pay the cost to respec into Frost, light them up, get what you need, and respec to Fire. It would certainly make it easier to do.
