Ok, quick suggestion that might appease those who say that Primals would be too big (even though they can be scaled down like in FFXI) and Yoshi-P who says that Avatars didn't look powerful in FFXI because if there were multiple Summoners in the same area with the same avatar out then they didn't look very impressive (though I fail to see how making Egis look like candy and corn fixes this) and doesn't require a huge rework of the job.

How about when a Summoner uses Enkindle (which is on a 300 second timer) then the Egi temporarily takes on the appearance of a shrines down primal? Still not quite what we want in terms of gameplay style/thematics but it's a start and wouldnt take that much work and Enkindle would feel more powerful, like how the signature move should be.
