Um I know this is kinda late, but here is what I kinda wanted SMN is FFXIV to be.
It's kind of hard to explain though, but I'll give it a shot!
When I first saw the artwork for smn, I thought the game play would be like Yuna in Dissidia 012 where she calls out the aeons to attack for her, not her attacking directly.
I think this can still work in XIV. Instead of Ruin, Bio, BioII, etc, the attacks would change depending on the egi that was summoned. The effects would be the same (DoTs), but just have the pets use them and change the name/animation a little to match the summoned egi. It's still a pet class, but it focuses more on the pet instead of the player. I think this would satisfy both the players looking for a "traditional" summoner and those who like the DoT style summoner we have now. I could go for a faster CD Enkindle too, but I digress! ^^;
Sorry if this didn't make any sense! Hahaha!
