I wonder if any current players could share some feedback on the faction/class population imbalances in this game. From what I've read so far, Sith are generally considered a "cooler" faction by most people. It's not surprising, since most fans of the movies tend to prefer the Empire over the Rebels. Personally, I also gravitate toward a Sith Inquisitor, since I have a predictable taste and I always play casters.
So, are some classes or roles overplayed/underplayed? Does one faction tend to have a larger playerbase than the other? Are there servers, where one of the factions is almost non-existant, like in a certain other popular MMO?
