To be honest, guys. I do not see a SMN class being implemented in FFXIV.

I think it's more or less going to be like abilities, not much different from what you'd see in FF7 and some other Final Fantasies where you could summon for a turn or two of assistance. In this case of FFXIV, it would be for a set amount of time. This makes more sense than having a persistent summon.

Though I'm not saying persistent summons are a bad thing - I loved having Garuda follow me around like some lost puppy in XI. :3
