And this is why I wanted this to be a Wrex DLC initially. He knows how to manage the krogan, how to truly set the species up for galactic society. Once he unites the clans, and establishes "peaceful krogan" (Heh, kinda an oxymoron, eh?), the undoing of the 'phage would be a good option. Wreav, with his traditionalist ideals, would indeed just cause the Rebellions all over again. Thus, the DLC would likely have Shep doing all the uniting, as Wrex might not be alive. The dialog would probably be different for Wrex though.
