[2021] Does anyone else think the Forking River map boss is way too strong?

I'm playing your normal bleed bow with 5.8k hp and winddancer and I'm struggling more with this boss than any other boss in the entire game, even Sirus and Uber elder are easier than this boss.

I have no idea what to do to increase my survivability against him. The big water ball one-shots me, there are rarely any mobs to keep my mana up or stack endurance charges and his own attacks deal way too much damage aswell.
I think my biggest issue with this fight is the range of those water ball explosions. I can't outrun them, so I have to dash, but I only have 1 dash and if the timing of the dash is slightly off or water balls spawn right where I dashed to, I'm dead.

This boss is way too overtuned imo.
