Alright, thanks for your feedback so far! In that case my last question is: Does the best amount of Es, As and Cs remain the same, even though there is a surplus in endurance and a lack in power when I use the crystal-vendor-gear?

That's right, the equipment I got so far is entirely purchased at the crystal vendor. So what you are saying is, that there is a difference in the balance of endurance vs. power between the modifications (?) of crystal-vendor-gear and operation-drops?

Hey everyone, since I started playing SW:TOR some weeks ago after a huge break, I was struggleing to find the right balance for my infiltration DD-shadow. Your thread did help me a lot, so first of all: Thank you very much. Ever since, I was aiming for the 216 Storymode-gear-stats, which are these: Assassin - Deception || Shadow - Infiltration 6000 DPS @ 49.1 APM | 6071 Endurance | 4969 Mastery | 2639 Power 1128 Critical (4xE, 6xA, 2xC) | 815 Alacrity (2xE, 7xA) | 681 Accuracy (4xE, 1xA) My problem is: Even though I now use the exact amouth of Es, As and Cs, which results in pretty much the stats that I was aiming for (got a little more, since I have 2 220 items by now), I have too much Endurance (about 400), too much mastery (about 200), while there is a huge lack in power (about 900). I am confused. I really am. Since I followed the "instructions" and critical/alacrity/accuracy are in the right position ceteris paribus, I have no idea where I went wrong. I'd really appreciate a hint for what I might have missed. Best regards!
