3rd Abyss Difficulty

So I got to the dragon and was promptly destroyed, it wasn't close. Fine, the event is not for me.

For those that started the 3rd Abyss at level 50 and did the event, how does it compare difficulty wise? Would I be fine doing the 3rd Abyss even though there's zero chance of me killing the dragon? I landed all the debuffs, they're all wearing water gear, he destroyed them, feels like its tuned for me to have full 3rd Abyss gear or something at level 50 and having just finished the second Abyss.
