Alright, knocked out a quick dungeon to get some preliminary feelings.
The Shear change is excellent. I ran a dungeon without Felblade, because that ridiculous talent change system is now in and I couldn't swap any talents, and the extra pain from Shear was definitely noticeable.
Fracture doesn't look/feel as impressive to use now, since the crits are separate rolls and are much smaller, but overall I think the damage definitely went up, especially when counting the extra pain generation from Shear.
Soul animations, seem to be much quicker than they used to be (look smaller I think?).
Soul Carver is a datamining error I think. It's definitely doing both the initial hit, and the dot still. I'll go with what Wowhead has and that it's 490% now and that's a buff.
Defensively, I definitely felt worse even with FTD, which I usually don't run in dungeons. (seriously, the talent restriction thing.... ) I'm really hoping that the magic portion of Demon Spikes is returned to us, even at half value or something just so that we can have somewhat consistent magic reduction.
Also, finally training dummies in the hall. Get wrecked on the raid tanking dummy.
