Thank you
I've actually changed my mind.
Maiev isn't going to turn to the Legion.
She is going to turn to the void lords / old gods.
At the moment, Maiev isn't in a healthy state of mind. She hates the legion. She hates Illidan / the Illidari. She is tolerating the I-squad's freedom because of the Legion threat. But she is running on hatred. And all the while... the void lords / old gods are whispering into her ear.
Her current state of mind is that the I-squad is being allowed freedom to deal with the Legion threat, but that once the Legion threat is dealt with, the I-squad will be put back in prison. That's what's keeping her above water. The "knowledge" that the I-squads freedom is temporary.
But the I-squad is vastly more powerful than the Wardens are. She does not have the power to put the I-squad back in prison. Not without the allied forces' power backing her.
Once the Legion threat is dealt with, she will turn to the allied forces for support to put the I-squad back in prison. She will not see this as a favor she's asking. The allied forces backing her to put the I-squad back in prison, to her, will be the only acceptable option. It will be what WILL happen. But... it won't. The allied forces won't agree to turn against the I-squad. Whatever transgressions they committed in the past, they served their punishment - 10.000 years imprisonment. And their help in dealing with the Legion threat is invaluable. They will be "forgiven" by the allied forces, and accepted.
This will put Maiev over the edge.
The old gods / void lords, with all their scheming and whispers, will convince her that all of the allied forces are corrupted and must be dealt with.
She will turn. To the void.
Legion's final raid will be a transitional raid to the next expansion (old gods / void lords) with a corrupted Maiev as (second?) final boss.
I know this is a lot of speculation (this is what we're doing here, right), but from my perspective, there's a couple of things that CAN NOT HAPPEN:
- Maiev can NOT accept the permanent freedom of the I-squad. Her hatred is too deep.
- The I-squad CAN NOT go back to jail. Because... DH class...
The combination of these two things is the basis of my entire theory. She cannot accept them being free, and they cannot go back to jail. That's why i believe she WILL turn.
