That's kind of an interesting point. They could have made the summons look like the summons, but size them like the egi. This would fit the concept of the summon being a fraction of the real primals power, but also give us actual summons. That and improving their use as pets would address most of the issues. It would also make XIV summoner different from other FF titles (at least the titles I know.)
Edit: The other thing that came to mind to me is this is Final Fantasy not EQ, or WOW. Final Fantasy has Summoners not Necromancers or Warlocks. FF summoner should be a summoner.
