For PvE, I think the changes will help their scaling in the long run. I suggested in another thread that we might need to make their Shadow spells crit at 200% in order for the Shadowform change to actually be a buff. But we are fully committed to having the dots crit. The game just works better that way.
Good old ghostcrawler, he knows just what to say to lift our spirits. Although, actually, now that I think about it, he's a little vague, and doesn't actually promise anything, and... oh well, it gives me hope :)
