Well when it comes to any feedback I give for the beta in WoD. I would be fine if the dotless spec were single target burst, mobility, or pvp oriented. But tbh, if the spec works out to be generally easier to play than the shadow spec, I wouldn't be happy if it was tuned over any dot-ful spec.
In general, I'd only be comfortable if shadow were tuned to play with dots in rotation for the majority of raids.
If I took that back, Blizz would have to surprise me with something really unique.
