Summoner is worthless in hardcore end game raiding. The reality is Summoner has equal to or lower DPS than the Bard but no utility to justify having all around poor DPS. DoT classes are meant to be crowd control but since cc's are spread across DPS they are no longer needed. Modern MMORPGS DoT classes are generally in the Healer role because they can multitask and provide party support. DCUO is the only MMO where DoT classes are designed as intended in the Controller Role. Also DoT DPS are easy to break. There are a few ways to fix the Summoner keep the job the same and design content around it which obviously SE doesn't want to do looking at FCOB and 2.5 dungeons. Buff the Summoner by 5-7% which will put them just below Monk. Rework the Summoner into a Pet Based Job.
