the key difference between the IA and smuggler class story well having both of them lved to 50 the key difference your find is:
The IA story is solid it kept getting better after each act
The smuggler story is a complete joke compared to its mirror i have never laughed so hard before, why you might ask?
the end of act one for the smuggler was incredibly rushed it was extremely bad now the IA end of act was very good because it was built up through the story very well unlike the smuggler the choices you can choice in the IA end one was amazing it really does make you think about it i lvled a op 3 times just to replay that compared to the smugglers choice if your a female you can kill shavak or have sexy time with him cba to turn it into a spoiler because i just saved you the time of lvling a smuggler to find out about the terrible story kthxbai =)
