The problem with the Summoner job is that instead of returning the job to its roots using Black Magic with basic white magic abilities and the ability to summon pets and primals they separated the dots from the Black Mage and gave it to the Arcanist.
They need to add Black Magic abilities up to Flare reduce the cd for enkindle to 150sec double it's attack power and add an ability to Summon the primal based on what egi is out with a 300 sec cd. We control the Primal for 30 sec when the timer is up it does it's signature attack and returns to the egi form.
