To be honest, the reason I rather not do Heroics or Flashpoints is because I'm worried I'll drag others down. I do okay with the solo-content, even some of the easier heroics. But as soon as it gets harder I have trouble, mainly because I don't really fully understand the mechanics and I'm lousy at tactics. I prefer the Healer or DPS role but apart from 'one heals, the other attacks fast' I have no idea what it entails. So, long story short. I'm aware of my shortcomings, realise I'm probably never really going to 'get it' so I don't drag others down because of it. Do I miss a lot of content this way? Yes. Do I miss a lot of loot and exp? Definitely. Do I also miss a lot of anger directed my way for not understanding something? That also but not everyone yells luckily.

And lets not forget that you get a xp bonus if you complete all the codex entries on a planet.

They are a pretty cool race lore wise, however, coding wise it would probably be a pain to implement. What I'm hoping for is that they add the Kiffar. Lore wise they are really really interesting and they would be easy to add because they pretty much look like humans with tribal paint slapped on.
