If you have 8 people on your screen you would end up targeting people you don't mean to... think about what your just said.... contradictory....

I finished Dromund Kaas 4-5 hours faster when I did everything by myself, rather than my other 2 characters that took around 14-15 hours to finish the main quest on Dromund Kaas

After finishing all of Dromund Kaas on my warrior I was level 15. I did not do a single group quest and I did not do the black talon. Will I fall far behind the level requirements for a main story planet if I continue to level by myself? Im almost 18 going into the final zone of Balmoora.

Anyone care to share?

Nothing you just said made me think that this game is not an MMO, you just complained about things you don't like. Also, I think the 8 stories refer to light/dark side. The choices you make for light will create different results than a dark side choice.

Are their any effects to your appearance if your choose to be a light sided player?

Im curious to know what dark side corruption looks like on every race. I have only gone dark side on my zabrak warrior and I cant really see a difference in appearance (dark side lvl 2). The effects on humans are very noticeable, what about the other races?

anyone?

Anyone have a link or a description of what dark side corruption looks on like every race other than the humans?
