I'm really enjoying Disc. I really hate mind flay for some reason, and I'm not a huge fan of DoTs, so shadow has a couple strikes. However, I do think shadow will be fun in PvP at 85 with mind spike.

I may try to play around with their specs and see how well they DPS as shadow. Although I'm happy with the disc DPS, I really have no idea if it's ridiculously low. For item level 217, how much single target DPS does a DPS class do? I'm going to try and find out with shadow, but I doubt I'll be doing much more than 2500 (I could be very wrong).

In other words, I will stay as disc as long as it's viable for PvE. For PvP, it will depend on how much burst penance is and how much fun mind spike turns out to be.
