I use it a lot in raids. If I dont need dps, then I use it. It's great for survivability. Ads are no problem if they cant see you. And the melting point is helpful for taking down VIP targets like the knights in Kali's fight. Truth is, you can use pretty much every subclass pretty much everywhere. It depends on how you use them. But again, this whole debate doesnt matter because whether or not spectral was "meant" for PvE, people use it there. PvP and PvE balance have needed to be separate since the beginning of D1. That's still the case.
