i'd say it looks pretty meh for destro, with afflic a close second.

demo has a whole rework coming for damage i assume, but it does have some nice tweaks. afflic is getting a coat of paint, and destro, well, it's probably still there.

biggest problem i have with cata is that warlocks don't feel useful or unique anymore. there's no evil, no good, it's rapidly becoming mediocre and second-hand to upgrades given to mage / priests / death knights, sic.

each time i see the cata warlock changes, almost makes me want to delete my warlock.so far, with the changes in spec, it might make me fall back to afflic or demo. i do miss the felguard, so, maybe demo/afflic will be the new vogue cookie-cutter spec.

destro, the one thing that still bugs me is the lack of variation, apart from soulfire being moved into the rotation, everything seems ... dull. genuinely lazy copy-pasted mage talents, compared to the thousands of repeatedly demanded user-posted changes to destro, arguably, is wrong.

IMO destro perhaps needs something with a bit of a boost to the mundane burden of DPS, i.e. procs, charges, something 'good', or in this case, suitably more evil and obvious to everyone that it's a warlock in the group, apart from glyphing the healthstone portal into a chocolate fountain, etc.
