Do you think pre Endwalker bosses are in need of adjustments?

Void Arc was even at release a joke. It just got worse by time.

Only tricky fight in there was the adorable Cuchulainn, but then Ozma came along and made him look like a joke. Void Ark is pretty much the Syrcus Tower (also a joke on release) of the Mhach raids.
Though I have seen wipes on the second boss in Void Ark, but that was because: people didn't kill the adds and also let themselves be eaten (the plant in the middle enrages if you feed it too much).
