Might have made more sense if it was put in right from the beginning, but it was made like that now it would be seen as a nerf.

I had an idea where you get a self buff that lets you have multiple egis summoned but you can't control them, they just cycle through their skills and enkindle attack on the main target before disappearing. Each egi may have some kind of effect for other egis (think dragoon lowering piercing for bard) which could be support or damage, and so you would think about the order of your summons while under this buff to get the effect you want. From there on it would make sense to bring in the ramuh levi and shiva egis.
