I just harken back to the origin of summoning in rpgs and ask thee to harken back to what the purpose of summoning vs having a pet is all about. You guys would be more at home with Beastmaster than with Summoner, from how I'm analyzing your preferences.
I can instantly understand why they said they would make Beastmaster a limited job now, because we already have a pet job and some don't want to seem to let go of their pet ifrit, garuda, titan.

Thought there would be more support for one attack summons, interesting that there's not.
