Yesterday I bought MOP and i started to level again my lvl 71 SP. But I've noticed that I never get single Shadowy Apparation proc, even if I have SW:P up on any mob as long as possible ... I only have 14% crit chance, but that should be enough to get it sometimes, i guess?
The other thing is, that my Psyfiend talent doesn't cast Psychic Terror ... And I have no idea why.
