I'd much prefer the Summoner ditch Egi's altogether and go the Blu route and just have summon themed attacks as part of our rotation.

Judgment Bolt and Eruption on Blue Mage is so much more a summon then what Summoner has. It's absolutely ridiculous.

Only fun parts of Summoner I find great is the Bahamut and Phoenix parts since they feel great and impactful. The rest just feels so lame.
