Good point, But if that were how does that explain her accolade of fighting an entire sith academy fill with Sith Trooper, Sith Assassins, Droids AND Dark-Jedi? her allies were not near her at all how could she have been 'strong' enough to defeat an entire academy and Sion? I mean I know that her allies don't have to be NEAR her, but Malachor is known as a planet that kills all life a bigger wound than the exile, when you think about it her allies were probably blinded by the powerful Nexus of malachor, I remember that dark side nexus' often lead to inexperienced padawans or master falling to the dark side or becoming blind(e'x like juhani who had a bond with her master, but after she "fell" she couldn't sense her master) doesn't that mean the exile was blocked off from her apprentices?
The Force bond with Kreia was unaffected by the strength of Malachor's Force nexus. There's no reason to think that the redeemed Jedi who followed the Exile would have a different experience. Rather, the damage to the Force bonds with the party would happen in response to the Exile's abandonment. She makes pretty clear that there's not much of a connection, and these sorts of bonds seem to operate on metaphysical/narrative closeness. Turning her back on the known galaxy to go find Revan would probably be one way to trim or sever such Force bonds.
