Well the idea is to give a bit more option as SMN, but it will never replace BLM when it comes to spells access and the damage dealt. If you want true proc from BLM spells, get a BLM - but at least this give a slight chance to help proc from the list of BLMs spell to SMN. It is still a bit inconvenient to swap spirits, but hey it could be nice. As for having Fire 2 and Fire 4 in the list, with spirits out, the idea is to have the spell list on your normal spell list instead being part of BP:Rage. This way you can cast as often as you want, it would consume the same amount as normal spells, and only available as long as that said spirit is out. But the damage dealt should be 20% less than normal BLM spells since SMN has no native elemental magic skills. Unless you sub scholar that is, then with dark arts you should be able to close match normal damage from BLM - should is the key word :)
