Talk among my static is the fight is just generally poorly designed and buggy. Heard other people say that out of the entire tier, its the worst fight to actually play due to how some of the RNG plays out, or how stupid some of the mechanics can bug out. As an example, if you mistime the bulwark swap during Hot Tail phase, you can lose the bulwark completely - as in itll disappear. Thats always fun. It's probably a server tick issue or something but even so...
