I do the same thing and its not because of the stories - I've done it in most mmos as well just because I love all the classes.. and I end up with a hybrid in most games because of that. Loved paladins/shamans/SK/druids in EQ - I never did get higher than 30 back in the day due to this and the fact that it was really hard at launch. Thinking back its just something with my personality because I went through 5 majors in college before settling on one.. so I have a feeling I'll end up jumping around with jobs in life too. There really isn't a hybrid that fills the void for me in SWTOR so its even worse, shadow comes close... which is another reason I enjoyed SWG so much at the start. I actually hate re-leveling at this point because I've seen most of the stories and done each planet upwards of 5-6 times (coruscant and taris probably around 15 times).
