How often do you actually make it to hundun/cosmic ocean?

I have about 200 hours in and the furthest ive made it is 7-1. I can get to and beat tiamat pretty consistantly but i cant imagine consistantly making it to sunken city. Honestly, up until the tablet it is smooth sailing but trying to make it with qilin and make it past the lasers is so frustrating given it takes me about 30 mins before i even get to that part.

Im ok with never beating cosmic ocean but i at least want to beat hundun. Do you all actually beat him consistantly or is it a decent challenge? It seems tough but i see so many people consistanly making it to the cosmic ocean so idk.
