Warlocks still broken

[trefer]

Hello fellow warlocks.

I am needing to know what mechanics/talents are still broken.

#1 Is pyroclasm still broken?
#2 Drain soul broken ?
#3 Amplify curse not working for exhaustion
#4 Drain Mana rank 4 missing
#5 Enter combat when sacrificing pet
#6 Is improved drain mana broken?
#7 are firestones working?

Greetings.

Pyroclasm was never bugged. The stun % is broken up by each individual tick of damage.
A fix for amplify exhaustion and drain mana rank 4 is done and should be on the server by the end of the weekend.

Work continues on other issues.

Thanks, finally. Any chance on a fix for shadow mastery not scaling with lifetap?
