The Summoner is broken in terms of balance because there is no point in bringing them to Raids besides nerfing your party. The Summoner use to excel at single target damage over the Black Mage until the Black Mage got buff. Now the Black Mage excels at both Single Target and AoE Bursts Damage which leaves the Summoner with nothing. It's the WoW Warlock all over again where the main reason people didn't like the class was because it was mediocre in every area the Warlock didn't excel at anything it was in the game for no reason at all.
