SE needs to remove the DoTs from the Summoner since they have never been connected with DoTs and posioning spell line that would be a Necromancer. Summoners base should have been an Evoker from the start evoking Melee, Tank and Caster in the form of Ifrit, Titan and Garuda gaining their abilities with glamours for the rest of them. Summoner in 4.0 should be a Caller with the ability to summon God like beings like Hydaelyn since she is the only one we know for sure that's a god or they can create Gods for Summoner to call.
