Well well, it seems the tier has finally been cleared. Over 24 hours is unusual for a savage tier. Looking just at the world first times for the individual fights up to 8, it looked like to be over quickly but the very last fight proved to be quite a roadblock. It seems when yoship was talking about the tier being more difficult a lot of that was about p8s specifically.
Congrats to Eis and their team!
