So uhh in the event your group finder for Veteran Flashpoints gives you Nathema and if after the Annex phase everyone else dies, you can solo it the rest of the way. Just saying so people don't think it's crazy to keep trying.

Yes its doable, i have done it four times now twice on my sent and twice on a commando dps. It takes the heal mech for the boss off the table soloing it, and you can just wear him down, work the koltos, and avoid the lightning. Then just stay out the red on the final burn phase.
