Savage raids were much harder back in HW that some consider A8s as the first unofficial ultimate. Gordias shattered so many statics from Faust to Living liquid. ARR coils and HW savage raids were the testing field for raid difficulty. That's why Gordias was overtuned that they had to nerf it. It's in SB that we got the official name for such high difficulty. Yoshi P also did promise people two ultimate fights per expansion in an interview. Their plan was to have one every odd numbered patch, but people said it was too rough, so they settled on two per expansion.
