The lack of a pet to manage does seem appealing as well as the more on demand burst with mind spike. I think I'll give it a go with the LFR and move it to my main if I'm liking what I'm seeing. Thanks for the input!
The only thing that might be weird is destro has less dots if im not mistaken. But they both work of a priority system, and not really a rotation type thing.
A good idea might be to set up some power aura (/powa! lol) so you can keep track of everything a lot easier. In terms of which is easier to play? I say a lock for the dps, but thats probably because I don't really like shadow at all. Shadow priests pull compeditive numbers also (I'm not saying that warlocks can't too though)
Another thing about destro compaired to shadow, I feel like shadow has much better dps when mobile.
