Thread doesn't matter, YoshiP was already on-record in an interview almost a month ago that they are okay with how it is, and having a final battle with some mechanic difficulty is expected. You'd think some people would remember simple things like breaking the chains from The Vault, but they get to level 70 and still can't do the mechanic.

As for 4.0 extreme primals which are kind of snoozer, Shinryu Extreme in 4.1 is supposed to return to something closer to Thordan Extreme was.
