[Game doesn't launch when hitting play......again]

Just adding my name here that I have a desktop that is having this same problem.

[Discipline Based Loot: Guardian/Jugg not working]

It appears that the boss loot drops for Guardians/Juggs are still not working correctly. My characters are Vigil/Veng, and I keep getting loot drops for a tank discipline.

[Phantom Stride after 5.9.3]

I have to agree, this additional GCD has done more harm than good thus far. I really hope the devs see this, and remove the additional GCD.
