Madness Heroic

[Mamorak]

Goodmorning Fellow Shadow Priests,

We are at the moment progressing on Madness HC and with the order we do platforms we always have +20% haste buff + timezone.
With DI from our lock plus the +20% haste buff i reach something like 65% haste. Should i reforge all my haste? And if yes should i choose mastery for better Mind Spike - Mind Blast on Parasite and Bolt ? OR should i go for full Crit in order to have Shadowfiend up more and proc the 4set bonus more often ?

Please let me hear your thoughts on this one.

Thanks in advance for your time and help.

Cheers,
Mamorak

Since you have DI haste is safe bet to go for, only fight in DS I dont go for full haste is spine.
