Hello, I found this odd, maybe not most useful exploit while leveling my sith warrior.
I advice players not wanting any kind of spoilers to stop read as I wont hold back any information (No major shit anyhow).
While questing on Voss, you will get the quest "The Voice of Darkness" (This is your class quest).
When you are finished with it, and asked to go back to your ship holocom room. DON'T!
Instead, you use the Emergency Fleet Pass (17h cd to imperial fleet) this way, you skip a cut scene (As seen here SWTOR SW Voss Class Quest - The Voice of Darkness - YouTube).
You will then keep the quest to go to your ship. This will trigger when you move to voss planet, you will get the next part of the quest. But this part will never go away.
End results. I have 4 different stages of my class quest. I can now farm any gear I get / loot / money / points from conversations.
I know this is going to be hard to confirm as you need to be at lvl 40+ ish sith warrior. But if any of you are there, enjoy this if you find it useful.
The marked quest is the one I can repeat. It gives "The transponder station", a quest to go to a ship, takes about 10 min to complete. Gives epic gloves + 15k xp + money, can do next parts as well.
EDIT:: Update ::
If you go to the cutscene planet hangar, anytime after you skipped it. You will no longer get to repeat the loop.
