The problem is clarity. It's implied that her plan might have worked if she killed herself at Malachor V. Why she doesn't is anyone's guess. The force bond isn't lethal. She died and Meetra was fine. Why was unclear.

She also knew Mira would be there when the time came and had the evil wookie bounty hunter waiting to hold her back from catching up with Meetra. Problem is that the Exile doesn't seem to know Mira is even there. The two never meet up. It's unclear how Mira even gets off Malachor since the Ebon Hawke is taken by the Exile.

Did she return to the ship? Did Meetra track her down before leaving? Hell in one cutscene we see the ship falling into the planet's core. How did we get it back? How many other party members are here?

Nothing is clear. Everything is hazy and open to interpretation. That isn't a strength in this case.
