Personally, I'm a fan of the FF3-9 style of Summoner. The one that called upon beings to rain death and destruction on enemies, or even heal and protect allies. With 10 and beyond, Summoner just lost it's feel to me and while I do enjoy Smn in 14, it's only because it's so closely feels like I'm playing my old Affliction Warlock from WoW. Personally I kinda had wished and hoped that with Summoner we could have gone back to the old style where you summoned a being to do an effect and then it goes back into the Aether or whatever it would come from. Like, for example, how Milla Maxwell in Tales of Xilla uses her spirits in combat.
