Loved leveling up. Was honestly surprised at that. Most MMOs you hate leveling and only endue it to get to the end game. Very well done all around.
Post 50 there currently isn't much to do. I've got a two full sets of cent gear. I've run the two operations. Messed with crafting not much of a point to it if you're not bio or cyber. Just out of reasons to log in. I like Ilum, or at lest the concept, population balance doesn't bother me I like being outnumbered, but Ilum isn't Emain and pvp in swtor will never be RvR.
So to sum up, I think Bioware did an outstanding job all things considered (lol NPR pun) but I've chewed through all the pve content and the pvp system hasn't been fully fleshed out yet. I'll check back in after ME3 and hope to re-subscribe.
