I think if they had just stuck with the look/feel of summoner from XI people would be a lot happier.

Now it would not be hard to change the current XIV summoner into something resembling this. We already have a good start because we have a way to do damage in our DoTs. They could change the awful Egi design and give us something decent to summon, but the summon would cost MP to keep out. The pet bar could be kept the same but change the 4 attack abilities to maybe 2 attacks and 2 buffs that are on a separate cooldown from each other. They cost a lot MP to use and have a 1 minute recast timer a la XI. SMN can choose between Fester (for more damage), or Energy Drain (To keep MP up)
