If this wasn't a Final Fantasy Title no one would complain about the Summoner but this is Final Fantasy XIV and people expect a certain feel and experience. Summoner's should get smaller and weaker replicas of the primals with a few tweaks.

Ifit- Eruption and Radiant Shield should be replaced with a Fire II and Fire IV Aoe
Titan- Weight of the Land and Goal should be replaced with Stone II and Stone IV Aoe
Garuda- Friction and Great Whirlwind should be replaced with Aero II and Aero IV Aoe.
