Can someone give me an in-depth explanation why Summoner is arguably the worst DPS?

I love this. The dps gap created between melee and ranged is just a complete design flaw with Coil's mechanics, and honestly, SE won't do anything about summoner's single target anyway, not to mention how limited summoner is with its aoe unlike blm so i don't even know xD

Also, my respect+ for those summoners who are getting top dps or at least trying to push through, you guys are amazing.

Thank you, we're trying :/
