The true fix is by removing the egi all together. Make the class like it is supposed to be like and that means making it summon mystical creatures that deal x amount of damage and along with it a certain effect that cannot be negated. This could add some really good burst effect to the class and also make it more interesting because it allows for more options then just keeping x pet out all the time. I know they want a pet class but honestly would rather just see it be more viable. I stopped playing my summoner sometime after release because it just didn't feel like a summoner. I would gladly lose the ability to have a permanent pet for some viability and on top of that they could use the true models at that point because they won't always be on the field and in the way of the players view.
