I decided to give this a try last week and downloaded it. I've been enjoying it for the most part, though for some reason once I get off of the starter planets, instead of continuing on I make a new character in a different class.
Right now I've got a Smuggler and a Bounty Hunter on Jedi Covenant, and an Imperial Agent on Ebon Hawk. I'm thinking of doing a Trooper on Ebon Hawk soon. Surprisingly in a game that focuses heavily on Jedi vs. Sith, I have little interest in playing either one.
Yeah, my first characters on both Ebon Hawk and Red Eclipse were troopers. However, I'm starting to really like my Jedi Consular (Shadow). I originally chose the class because they can use the double-bladed lightsabers. I noticed the last few times I've played though that I never use the lightsaber. The JC has a lot of mental and telekinesis attacks that are much more effective.
