Joining Shakturi alliance?

[aZmoDen]

Hello, i always play with the RotS story line enabled and i always join the ancient guardians.
However this time i wanted to play on the evil team.
However i am not sure how to proceeed.
I have started a FTA with the ER, and chose 'i do not care about your freedom aliance' when the ancient guardians spoke to me.
However even with a +20 rep with the Shakturi, they wont accept a MDA.
Am i missing something? do they give me an option to join them like teh Guardians do? or do i just have to plug away at the MDA?
Or have i messed up the options i need to get this going?

Hope someone knows whats to do cause i sure as hell dont

Can't you destroy the Guardians, and then turn and destroy the Shakturi? Seems better that way, why share the glory with a bunch of worthless bugs...?

I mean you'd always have to be the lesser partner right? That just doesn't seem right.

I don't think there is a specific equivalent to the Guardian's Alliance with the Shakturi, just the can't beat 'em, join 'em achievement thing at the end if you go down this route.
Other than that, bugs just tend to have fairly high base thresholds for diplomacy stuff.
