So, this is obviously a personal opinion, but I just started playing an Inquisitor (just hit level 10) and so far it is SO MUCH MORE FUN than my Shadow at level 25.
I played WOW for a good while and always played Alliance because I liked playing a good guy, but the story, the companion, the look and the abilities are all so much cooler on the Inquisitor. Not comparing light to dark choices and what not, the story is just so much more interesting so far for the empire. Your master is obviously a better choice over the Consular's for obvious reasons and your first companion is a BAMF and the way you have to get him is just a great progression.
I'm not one to agree that Bioware likes the Empire way more than the Republic, but it seems like they really got into the Empire story while the Republic was mostly "this seems like a good deed, so we'll put these choices in." Also, in the choices you make for light and dark side, the Consular is so obvious what's good vs evil, but for the Inquisitor, it's like "What? That's the light side choice? Really?"
What do you think about this? I may be posting in the wrong thread, but it seems like a class deal.
