I can understand the frustration with this since I was also very disappointed by summoner but they have stated that they will not change the appearance of the Egi because it conflicts with the lore. They will however add new ones when the level cap is increased.

Additionally though I think that titan can offtank just fine, he shouldn't be comparable to pld/war in my opinion. As far as ifrit and garuda go I think they're doing ok as well once you get used to managing your pets properly. My biggest problem with summoner is how underwhelming Enkindle is for its 5 minute cooldown. Aside from that Smn can pull top dps in a lot of fights if they are good so I don't necessarily want to see them get buffed either.
