By that I mean the kill target gets disabled (e.g. kidney, horror, leg sweep, etc.), in a lot of cases the healer gets CC'd and damage commences on the kill target (you). For Void Shield to be effective, you'd need to do some serious damage, but that means blowing your damage in order to just keep yourself alive, and that's assuming you have your damage ready to go (you also have to blow a GCD just casting PWS, which may or may not be significant, esp. if you're getting spam purged by enemy healer/enh shaman). It just seems like it's too conditional of a talent to be GREAT. I'm not gonna deny that it can be a god send, but it's just a bit too situational for my taste.
That said, the turn around potential if you have your insanity ready to go sounds freaking awesome. And hey, the meta might just change in Legion (it'd be nice!) So who knows! In some sense, you can view Void Shield as a minor amount of additional effective mitigation that requires no additional GCDs (because you'd naturally PWS in those situations anyway), and that might translate to just the small bump in tankiness that spriests need to be arena overlords.
