Make RNG and make it super strong from ranged! Call it Musketeer, and make each attack take 1-3 seconds to use. Trade mobility for damage. Trade utility to keep your range at the higher dps rate. Then you can be a BLM with different animations . . . As much as we would all love some new jobs to come in, they need to be brought in properly, and it's VERY rare that anyone has a good idea for implementation.

I could see a buffing job coming soon, haste exists, enspells exist, spike spells exist, paralyze exists, but only for enemies right now... but at least they're there already.
