Forgive me if I am wrong, but the only step to trigger this bug was to have picked a talent. The rogue exploit involved engineering a specific circumstance highly unlikely to happen naturally. I can see rating adjustments where necessary, but I think that a bug that passively happens from normal gameplay shouldn’t result in account actions like a bug that requires specific circumstances to exploit.
I don’t think anyone should be outright banned for the phantom pain bug, because like you say it was different. However, the hunters who obviously shot up hundreds of rating after being hardstuck should definitely be lowered back down to where the were and receive some sort of warning. It was painfully obvious what was going on, pun intended, and they made the game aactively worse for everyone else. And blizz deserves a warning as well, but the playerbase is apparently more than happy to eat up the new 90$ sloposaur.
I agree with this, the only edit I want to make is for high end players who did it. Multi r1 players knew immediately that it was broken, many refused to heal the players doing it. We even had an AWC competitor abuse it.
