Plus history has shown that one way or another, MMORPGs will steadily neuter and/or remove their pet jobs as they age. I don't know exactly why (since it should not be the same for different MMOs), but it happens, so it seems to be some universal constant of MMORPG-design.
Which is why visually giving us those huge FF-style summons but mechanically making us do a lot of things and just showing the summon doing it ("us giving commands" kinda) would work so well.
