You don’t need to see any leaks. Blizzard has confirmed this is the last raid tier of this expansion.
I think Torghast is fun now. Playing Jailer’s Gauntlet not for any specific need but because it’s fun. There are alleged leaks that 10.0 is going to launch with a feature like Jailer’s Gauntlet, which I pray is true because it’s actually quite solid and would make for a fun feature to play if it didn’t get weighed down by the negative labels associated with Torghast.
