I have an Intel 3930K 6-core CPU and two R9 290X's in CrossFire, and yet when I play TOR I get these microstutters that are REALLY annoying. I'm running the latest drivers and there's no way this is taxing my system, so I'm at a loss as to what is causing this. Would appreciate any advice.

So, I now have lvl 400 in both Scavenging and Underworld Trading and over the process of running these missions I've noticed that it always seems harder to find missions for stuff that I need. The best example is in Underworld Trading, which has Luxury Fabrics, Companion Gifts, and Underworld Metals, and only the metal is useful to me in crafting...but it seems like there's some sort of maximum number of times you can run a mission before you need to run other missions, and I'm not just talking about a mission being unavailable while someone is working on it. I mean, there are times when all my companions will be free to go on missions and yet there will be NO underworld metal missions, so I'll be forced to run a companion gift mission until a metal mission appears. It gets very frustrating and I haven't been able to find any sort of rules for how this work, so I could better predict and plan which missions I should go on. Any help would be much appreciated.

So, before anyone states the obvious, I KNOW Sentinel isn't a tanking class. What I mean, is that there have been times where I've run Flashpoints at the limit level before they grey out (and other times when they ARE grey out and I'm running them for some quick creds or just to try out a different spec) and I find that I have much more HP and armor than the others and we don't have a tank. Anyways, outside of specific skills that generate aggro (of which, I believe Sentinel has none) I'm not sure exactly what CAUSES aggro, I just know I have an awfully hard time maintaining it in a group of 4, especially with a healer, which I'm constantly trying to pull mobs off of. Anyways, outside of Force Stasis, Pacify, and Force Kick (which isn't always useful), are there any other ways a Sentinel can pull mobs off of ailing players in a group with no tank?
