Hand in at any time you want, but to get it done in one swoop you'll need 20 salvage.

I've always wanted a purple color crystal for my lightsabers, but I'm unsure of how to get them. I'm fairly sure artifice is required to craft them, but then how does one get the schematic to craft them? I've seen the crystals can be purchased on the GTN, would buying one and RE it work, or do they also drop from HM Ops/HM FP's?

If the companions were not helping in deactivating the shield, alarms, and the EMP. Then they were clearly not intended to be of any help in that quest, aside from helping clear out the enemies. If they were meant to help with the puzzles, then they would do so. Just group up with random people to get it done, then be on your own way. If the OP is against grouping with others to finish a mission, then it is not the developers fault. If companions were intended to fill out a group as you said, and I completely agree with that. Then the companions may as well take an active role in all dialogue options during group missions. I don't recall watching or hearing anything about the companions being intended to solve puzzles, if you would like to provide a source from Bioware stating that is one of their functions then I will take back what I have said.

It clearly says it is a heroic 4 quest, it's expected that users be able to understand that it means it was suited for 4 players to complete. It's not the developers job to put a warning on everything because you were too impatient to fill up the other slots with players.

So whenever I log in, I see a large amount of people cluttered around the GTN vendors, buying and selling items. People by the crew skill vendors sending companions out on missions. I was thinking that perhaps it could be more beneficial if a browser add-on, iOS/Android or even something added to this site itself that could allow users to access their accounts to send companions on missions to gain resources, maybe make items depending on their skill. Access the GTN to buy and sell items (would need to log into their character via the main game to receive the items they buy) And other options, without actually signing into the game. It could potentially help those who are unable to log into the game, or just do not have the time to do so. By having an iOS/android app, they could access these features on the go.

Wouldn't it also be possible albeit in a strange way, that his mask was the foundation for the Kaleesh mask. Seeing as how the Kaleesh view death as a way to godhood, isn't it possible that viewpoint began with Nihilus becoming the way that everyone knows him as. Personally it somewhat makes some sense that viewing someone who should by all right have died, but survived only for his body to eventually die but still live on as Nihilus did. To me, it does seem like a plausible way to explain why the kaleesh way is that only the strongest ascend to godhood after death. Seeing as Nihilus' body died but he lived on, the kaleesh could view that was an ascension to godhood and wear similar masks that evolved with the times as a sort of symbol.
