The only worrying thing for me so far is how easy it all is. I've only gotten to 11 with a smuggler, but I've been blowing through the content on autopilot, haven't even come close to dying - I think I've used a medpack twice in all that time. Once I got the first companion it just got silly.
Hopefully they're just going easy on you because it's the starter planet. No challenge = bored.
I had a harder time with the Agent, weirdly. When I played Smuggler (to see if I preferred Empire or Republic), I just breezed through the entire first planet.
I'll still be getting this. I liked WoW, but I don't like the swords and spells style fantasy settings in these games, and this solves that problem.
I had my heart set on a Bounty Hunter before I played the game, but now, I can't tear myself away from the cover classes. I'll be rolling Imperial Agent come release. They sound so cool

Anyone else plan to play a certain class, and completely changed their mind after playing the beta?
