Make co-op / multiplayer please!!!!

I've been trying the new boss but found issue with damage the boss deals. Without proper defensive set-up, the characters cannot survive his first mechanic. Switching to the bare minimum defensive caused me to hit a 12% (!) enrage, which seems extreme. I've never run into such a severe problem like this, the boss seems very overtuned. Am I missing something?...

Look, I know most of the patterns. I stay away. I don't get hit by the lightning aftershock in the water ring. I take vulnerability with archer and defend at 30% with knight. but the latter half is insane. you need knight to go close to bats to kill them but the lasers have an insanely wide hitbox and the water gets shocked. my very best is 2 stacks, 3 is more common. then, right after you get hit he throws two all-arena AOE spears which even with best positioning and 30% defense would do 200+200+200 light...

For those unaware, the big fights show are Ifrit, Garuda and Titan. These fights are ripped straight from Final Fantasy XIV. Like Nothing except enemy models are changed. They are identical fights. Don't exactly think that you can just do that.

Thank you for the game. It's a hidden little gem! I love boss fights and skipping all the "in between" is amazing. This game managed to capture boss fights by introducing a unique mechanic (control two characters), it fits right in the genre "boss rush" (which is ambiguous, sometimes is just a single mode in a whole game), I started tagging these games "MMO Gist". Either way, I love that's single player, I've been playing TrinityS with my wife (similar thing) but we can't seem to find a third player that'...
