I kind of wish they'd rework summoners so that the primals were abilities instead of pets. The only pets you get would be carbuncles and then you learn special abilities involving Ifrit, Garuda and Titan.

For instance, Ifrit could give you a stun and a physical attack. Garuda gives you a DOT buff and magic attack. Titan gives you a knock back and Pet buff. When you use the abilities, a smaller version of the primal (no egis) appears, performs the ability and then disappears. Your Enkindle ability would be a placed AOE with one of the three appearing randomly to perform it.

This would do quite a few things for the class, IMO. First, it would make each summons useful. No more shunning one or two and never thinking about them again. Second, it would make a summoner actually feel like a summoner! Instead of being stuck with one pet/summons all the time, you would actually summon a multitude of primals to do your bidding during every fight. Last, when they add more primals, like Leviathan, instead of him being the new pet that you're likely forced to use, he would just add a couple more abilities to your repertoire.
