This would allow for special summoner quests say with the release of any new primal or even certain trials where they can add a new summon to their list. Some summons would definitely be used more than others but if they were all unique with different effects, no one summon would ever simply not be used.

Then buff summoner basic spell potency to make up for losing their pet and BOOM suddenly we have an ACTUAL final fantasy summoner class and have room for the beastmaster class because now there's no pet class anymore.

Thoughts?
