These are for WoWhead and should be able to be imported in-game when servers are up.

Augmentation -

And version two of the aug build, takes molten embers instead (I have yet to try this particular one, my friend thinks it works a bit better)

And a third, keeps prescience but aims for dream of spring

Other two builds for it, maybe could get rid of perscience cause it is more for groups needs an ally…if all you do is solo. But I personally like it cause it helps people around me so I choose to keep it. The augmentation builds especially can be tweaked to your liking, preservation I find plenty good as it is.
Why Augmentation for solo and not devastation?
Does a decent amount of damage, BUT not as much as devastation. Scalecommander doesn’t solve that as Chronowarden is just way better (for both specs) even solo.
The real thing is, ANY and EVERY class can solo world content so that isn’t special actually. Except what is special is not every class can solo elite world multi million HP bosses solo if no ones around and even less can solo equal level dungeons, and low tier mythics. In the end of DF before I changed servers, I as preservation was able to solo a the first tier mythic even after mythics got buffed. Devastation is too squishy for that despite the damage.
To be upfront, I haven’t tried it in Augmentation (it was worse off in DF if solo) as I’m still leveling my dracthyr, but its buffs all around to solo dps and survivability. So I’m very interested to see how far I can go with one.
On to preservation.
Kinda self explanatory. But why be a tanky caster (or healer I guess) when you got warlock? The in the past (PAST) it was the tanky caster.
Not anymore. Warlocks got hit hard with self sustain in TWW, and throughout DF their sustain got nerfed from launch. A huge hit to leech and drain life in TWW, and the voidwalker holds agro as good as a priest tank would hold agro…as in not at all lol. The answer you get is “well slow down then”, then my response is why play and instead just make a mage who have a laundry list of defensives lol. Not slowing my gameplay down, survival hunters don’t have to and they are tankier than warlocks in TWW and even BM their pet holds better aggro.
Point being, warlocks are no longer THE tanky caster in DF. Yes they have some sustain and are still sorta tanky, but kinda like if you removed the outer layer of a egg shell…its still there same shape, but not what it was.
But you are here about preservation…
When I’ve been leveling one, it does kinda seem like they actually do good damage, maybe more than augmentation (but I tweaked the aug build around so will see later). And the amount of heals and sustain and defensives make them THE tanky caster spec in the game. In DF, as I said, they could do insane solo achievements that most classes couldn’t do and meet the dps marks doing it. TWW turns that up a notch with chronowarden, its obvious this is the TO GO TO spec if you want a dps ranged “tank” that can do insane solo content.
However, I find augmentation to be more involved than preservation and I like the effects more. So will be messing with the various builds for it quite a lot.
Hope this helps, I put the builds on top and details down below and why play them and not devastation (which I find can’t solo nearly as much as augmentation and especially not preservation) or another ranged DPS (though if you were wanting a dps tank and didn’t want to be evoker for whatever reason, survival hunter is the other dps tank right now).
Saying all that to end off this long post. If you like devastation and it works for you, thats great of course 
But if you want to go as far solo as possible, preservation and maybe aug is better. And obviously I’m no pro or meta gamer, in fact these builds might suck so much even for solo i’ll be laughed off the forums onto another character lol. but at least preservation build works really well for me, still messing with the aug ones.
