Summoner should be reworked to be like Yuna in Dissidia https://www.youtube.com/watch?v=xSUlkgS4vO8

Instead of having a separate pet, you have GCD's that summon a Primal for a split second, they do their attack, then vanish. So you swipe your hand on your Gimoire, Shiva appears and does a Heavenly Strike, then vanishes, then your do another GCD, Ifrit comes out and does an Eruption AoE, etc. That's how it SHOULDA been instead of this Egi crap.
