okay. All of the people who wants the current summoner that is branching from arcanist to be re-designed: There are people who enjoy the current summoner as it is and they don't want any changes to happen for it.
So, instead of trying to re-design the current summoner, as it's linked to arcanist, which means you'd have to re-design arcanist also, which means you'd also had to change scholar's base spells that come from arcanist, what 'bout you'd ask the re-design in this way:
  1. New Job without a base class called Summoner.
  2. Current Summoner re-named to something else.
  3. Current summoner's job quest skills reworked
  4. Current Summoner continues to use carbuncles(because scholar still needs the arcanist base class skills called Summon + Summon II(those skills should be renamed if this is going to happen)).
  5. The new implemented summoner would work more summoner-ly like most of the people who are unpleased with current summoner wish it to be.
  6. Everyone's happy.
