I'm also interested in this, my current aff stats are:
Haste: 7221 = 16.99%
Mastery: 8303 = 67.70%
Crit: 1919 = 11.29%
In my raids I really dont have time to have to reforge before every other fight especially when I'd have to go to the Shrine to do it....
I don't have simcraft as I'm at work atm so I have no clue on how those stats would perform for Destro.
Those stats are almost identical to mine, I've got about 600 more haste - I believe you should be able to play destro fine, but as I said earlier, it won't be optimal and you might run into GCD issues with affliction haste when you've got large haste procs.
Just bear these things in mind.
a) The difference between destro and affliction shouldn't be huge (unless you're bad and good at one spec and another).
b) The difference provided by reforging, while certainly worth it to minmax, shouldn't be gamebreaking
c) Lots of guides, such as Brusalks - are aimed at squeezing out that extra 100 dps
If you're fine playing suboptimally and you don't care about that extra 100 dps, that's fine - it's your choice, you can play destro with affliction reforges and you should be able to do enough damage to compete IF you play well. On the other hand, the gap between affliction and destro is so small that there aren't many fights I can think of (bar meter padding) where destro will outperform affliction, especially when played suboptimally, and vise versa.
Which makes me think, in general, it's better to just pick one spec (since both are perfectly viable) and aim to play it optimally, rather than dabbling in both - if you want to play destro, that's a perfectly legit choice - why not reforge for it? If not, afflictions still perfectly competitive.
That said, if you simply want to switch between the two on the fly, yes - it should work, but you won't be squeezing everything you can out of the spec if you're doing this, it's up to you to decide if you and your raid group can deal with that.
If all else fails, you can always try raiding as destro for a week or two with reforges and see how you do, then compare it to your previous or future affliction runs - see what works best for you, reforging once a fortnight isn't a huge pain, especially with reforging tools like reforgelite.
Not entirely on topic but very related, since I couldn't get any posts in my thread I'll respost it here to see if I can get some advice.
So I dropped my Aff spec for destro, but I still mostly go Demo on fights. I'm trying to figure out a good set of reforge priorities (in general) so that I don't have to reforge every time I switch (or try to gear two specs differently)
Seems like the general case for Demo is Crit = Mastery > Haste, and for typical single target destro its something like Haste = Crit >Mastery using GoSup. Both specs seem to favor crit but Im not sure what to do beyond that.
And I constantly go OOM. I'm sure it's just not meant to be played with that much Haste, and obviously it doesn't help that I have a Haste trinket.
It's not part of the single target rotation this has been discussed on many threads. Why would you call me out for using RoF (which is not the case) and going OOM and then turn around and say I should be doing that?
The reason from, what I've read, not to use RoF is because it makes you go OOM... you are very confusing.
Being OOM is not the worst thing in the world as Destro.
Also, I'm the person who's done pretty much all of the theorycrafting of Destro since 5.0 that's publicly released information (at the least on here).
You should re-study Destro as it's pretty apparent that you're not understanding some things about Destro that's publicly available and is the general consensus.
Played some bosses yesterday with affliction/reforged gems as destro.
- Jinrock: terrible
- Horridon: awsome, 98,6% ranking with 503ilvl. It's more a matter of skill than equip.
- Tortos: not bad, again it's more about you than your equip.
You must not be keeping RoF up enough. I go oom very often with waaay less haste.I'm playing with 3k less haste than you and never go oom...
