Evil only wins when it spreads. It can cause destruction, it can cause death—but those are consequences of its nature, not its victory. Not its goal. The danger of evil, the purpose of evil, is that it causes those who would oppose it to become evil also.

We know that the heretics of Avaloren proved, for whatever reason, too strong for Odyn's forces. And what force was hinted in Time Rifts, at being able to crush the Keepers and push them into hiding? Life. Apparently, if the Void corruption was completely eradicated from Azeroth, the planet would be overrun with Life. Back then we didn't have an explanation why that would be the case, but now we know about Elun'ahir. It's fair to assume that the cause behind this wild spread of Life is Elun'Ahir. And this leads to two possibilities:
* First option, with Old Gods being fully eradicated, the Titans left Azeroth early, and Aman'Thul did not pluck Elun'Ahir from the ground before that. Left alone, it caused the spread of Life.
* Second option, Aman'Thul DID pluck Elun'Ahir from the ground, but the roots stayed in the ground. The roots, given time, caused the spread of Life. So, why didn't it happen in our timeline? Perhaps the roots were somehow hijacked by the Old Gods?
With the last raid being Life-themed, could the next expac be Life themed as well? Or Life/Void, just like that one unnamed Old God with vines for tentacles from the drawings found on margins of Chronicles?

I mean we have at least two examples where "as long as you believe, they are willing to give you the power" basically just paraphrases into "You accept us, my way or the highway, or .. maybe you just die." - Xe'ra absolutely tried to force the light on Illidan and Yrel's lightbound in AU Draenor definitely gave everyone and their mother the option to join them, but that doesn't exactly counteract the fact that for everyone not joining up willingly, it was basically a holy crusade approaching, that will either force them or kill them.
Getting some cosmic weapon triangle vibes here, and I think I could get on board with the implications. For example, the forces could naturally balance each other out through their respective strengths/weaknesses against the others. Except for where something goes awry, like Life growing uncontained on primordial draenor, or just everything about Azeroth.

We really only have the fact that Xe'ra (and Au Xe'ra) is a bit of a dick for a downside of the light and even then we know that not all Narru operate the same way as her or even have the same goals as some were against her plan to use Illidan and instead wanted him dead for his crimes.
We then have what, the sliver hand, scarlet crusade, blood knights, goats both zealous and not, and who knows how many other cultures using it in less obvious ways like the sun walkers and the light asking nothing in return and doing nothing bad to any of them.

I mean, the story in WoD would end up on peace terms no matter how they choose it to end or if WoD would be properly developed, the war had to end.
If Grommash would be the final boss like it was planned, after killing him you would have durotan that would choose peace with Yrel, because they fought side by side.
Yrel went craazy with light after years of peace and decided to go with her crusade.

It makes sense that they would live in peace after what they went through in WoD. It doesn't make sense that Grom is both totally hunky dory instantly and also the ass pull bs of saying Grom mister "We will never be slaves but will we be conquerors" is the good guy in the situation versus Yrel the one who actually gave a shit about the people around her and didnt want to just casually genocide anyone.

Sorry, hadn't seen that portion of the discussion. I perhaps should read through past posts more, but with 1760 pages I tend to forget such things.
On that note, I agree that we'll get multiple support specs if any are added. There's no good reason to only have one in game for more than a short time. I could see a good 5-6 being added for various classes.
I'm not so sure that I agree on the 4th role, if for no other reason than how it could create a bit of a bottleneck for LFG/LFR. There's already a bit of a wait for DPS players to get a healer or tank, not sure adding another role on top of that will do great things. Plus what do you do with the grouping layout for dungeons? Do you stick with 5 mans and have 1 tank, 1 healer, 1 support, and 2 DPS?
