Everything I've heard is that BW's failure to address the server issue caused almost all of their problems. People got tired of playing on servers with a dozen people on them or less than that and quit the game entirely. I can't say I blame them.
I really want to play a Republic character, but none of them really appeal to me. I would love to play a Jedi, but I tend to suck at melee characters and I'm willing to bet there are a bajillion Jedi running around. I'll probably end up playing a smuggler or a trooper over there. I'm told the Imperial Agent story is interesting.
I usually play for 2-3 hours in the evening which is a huge time waste, but it lets me unwind after work.
