Let me help make one of those decisions for you: Don't do the GSI dailies.
Galactic Solutions Industries terminals can be found on Alderaan, Hoth, Tatooine, and of course, Makeb. Each terminal hands out five daily missions with one weekly mission shared between them. But that's not important because I'm suggesting that it's not really worth your while to do these missions. Why?
According to lore, GSI was founded by inventor and tycoon Addalar Hyland on Nar Shaddaa. Having seated itself in the middle of neutral territory, the company was in a prime location to make money off both factions. Hyland's first major product was the GSI-B4 blaster pistol known to pack a powerful punch for an easily concealed weapon. However, most people are now familiar with the GSI industrial-grade Seeker Droid. This droid was originally designed to extract subsurface detonite mines. Now, Seeker Droids have been augmented to perform many different kinds of subsurface extractions, especially in hard-to-reach areas such as mountaintops and sea floors.
Time: 45 minutes
Each of the planets I listed above has a set of missions that require you to use both the macrobinoculars given to you during the Shroud questline and the Seeker Droid given out at the beginning of the Dreadseed questline. And although those two questlines are rewarding, the daily GSI quests that coincide with them aren't really worth running more than one time apiece.
I mentioned time vs. reward above. The biggest reward gained in SWTOR dailies is money -- credits. I've examined the primary set of dailies on Ilum, Black Hole, and Belsavis. It takes about an hour and 15 minutes to run all of those dailies. And in the end, I gained 189,057 credits, which averages to about 2,520 credits per minute. The Section X dailies gave me 67,427 credits and originally took me 45 minutes, averaging 1,498 credits per minute. (However, I've become significantly faster since the initial report; it takes me only about 30 minutes to do the whole run now, which would make me 2,247 credits per minute.)
In contrast, the Tatooine GSI missions, which I think is the easiest set, gave me only 53,470 credits. (My totals include credits from mobs, greys, and vendored armor pieces, minus travel cost, if you're wondering why the total differs from other guides.) If you average that with the amount of time it takes for me to do these missions now that I know what I'm looking for (45 minutes), it averages to only 1,188 credits per minute. Let's say that I am eventually able to reduce the time to 30 minutes; that would still only make the CPM 1,782. That equates to 69,300 credits lost by doing the GSI quests instead of the other dailies. The weekly 19,642 credits earned from the Valued Partner Initiative quest does not make up for the credits lost. And if you're thinking that your results will vary because of the different mob encounters, bear in mind that only the four Heroic +2 missions have any sort of mobs to fight at all, and even then it's only one mob per quest.
Here's the wrench: The GSI quests give 6,940 points in GSI reputation. And the only way you can purchase items from the GSI vendor is to have good standing with GSI. There are certainly coveted items on the GSI vendor, such as the GSI EMP-03 Explorer speeder -- the one that looks just the like speeder from Return of the Jedi. However, I say "meh" to that and pretty much everything else on the GSI vendor. The only cosmetic items worth the credits, in my opinion, are the ones that drop from the Cartel packs.
With each set of dailies BioWare produces, the overall gain is less and less, yet the money sinks like armor repair cost continue to increase. I'm not exactly sure what the devs have in mind, but I hope it pans out in the end. I seem to be losing more money than I'm gaining, which is ultimately not going to make me a happy gamer -- and I'm not alone.
Next week, I will begin my free-to-play experiment. I have proclaimed that I believe it's possible to play free-to-play and still have nearly everything you want, if you're willing to invest the time. If the experiment is successful, I should have a character doing endgame raids and flashpoints by the middle of next month. I will keep you updated on his progress in future issues of the Hyperspace Beacon. This should be a fun, honest experiment. I hope you look forward to reading it as I have doing it. See you next week.
