Good call, I fixed the OP.
Some thoughts based on feedback thus far.
SMN as a pet class and my approach to final attacks aren't mutually exclusive. I didn't note this in the OP, but I thought that FFXI had a neat concept with the elemental spirit summons. When soloing, partying, etc, an elemental spirit would be good for all-around utility. (just make it so they are actually affordable to maintain, unlike FFXI)
For those that have played FFXII Revenant Wings, you'll remember that there were actually tiers of Espers to summon. A good approach as it gives variety and progression to the SMN job. For instance:
- Rank I (Earth): Earth Elemental (no MP consume)
- Rank II (Earth): Golem (FFXI style summon - Low MP consume)
- Rank III (Earth): Titan (FFXI style summon - High MP consume)
- Rank IV (Earth): Hashmal (Instance only)
- Rank I (Astral): Astral Elemental (no MP consume)
- Rank II (Astral): Carbuncle (FFXI style summon - Low MP consume)
- Rank III (Astral): Alexander (FFXI style summon - High MP consume)
- Rank IV (Astral): Ultima (Instance only)
- Rank I (Umbral): Umbral Elemental (no MP consume)
- Rank II (Umbral): Fenrir (FFXI style summon - Low MP consume)
- Rank III (Umbral): Diabolos (FFXI style summon - High MP consume)
- Rank IV (Umbral): Zalera (Instance only)
Come to think of it, FFXI went down this multi-tier road slightly with Odin and Alexander...
Another good idea~
