I did get significantly better stuff after leveling up at the spawn point, but only lightsaber crystals. I usually do Korriban last, so not much loot to be found after that.
I know how! Have an incredible amount of free time and stay at the Infinite Hssiss spawn point for days until you become level 50 :D
Is that even possible?
You can get the 2 of a Lightsaber when you rescue Jorran and fight Visas on the Ebon Hawk. There are other places or events where you can get the same parts, but I'm not sure where.
Both. You need to be in solo mode to activate stealth, and it doesn't go off only if you have stealth on, and have a good repair skill to deactivate it.
You're not gonna play it again because you have to start over?
And if you do play again, try saving in different slots. Helps when you do something wrong, but deleting them afterward takes a hell of a long time.
Exactly, never. I have the Xbox version too, and mine doesn't slow down too much, only one or twice where I was fighting over 10 enemies at once. Try deleting some of your saves that you don't need, that might help.
No, you don't have to start over. (I think.) You're not supposed to go to Telos. Telos is after you've been to the Rebuilt Jedi Enclave on Dantooine and after Kreia has killed the Jedi Masters, for LS. Then you have to go to Telos to save the Handmaiden and fight Atris.
But if you've already gone to the rebuilt enclave on Dantooine, then you may have to reload/restart your game.
