It seem's for many people who main Summoner they have been left feeling a little underwhelmed. Are there any plans to overhaul the Summoner to address these views?

Perhaps this is because the Summoner is far too focused on D.O.T based attacks and the actual Summon (Egi) kinda fades into the background. Maybe something more like Aion's Spiritmaster job would be better suited to fill the role of the Summoner. The Spiritmaster's summons in Aion start out looking exactly like the Egi, but they grow and evolve with the Spiritmaster eventually becoming the size of a mount. I feel a system more like this would benefit the Summoner greatly as it shifts the focus onto the actual Egi and works with the jobs lore. Since a Summoner can only manifest a small portion of a Primal's aether. However as they level surely a Summoner would be able to control greater quantities of a Primals aether and therefore be able to summon a more evolved/formed Egi.
