The whole SWTOR economy is based on money sink. You are supposed to grind dailies, to spend money on various money sink (legacy, mod swapping, augmentation...). It's not healthy at all.
Which is counter to BW's claim that this is an "alt" grind game. If you are spending time grinding alts you are not necessarily spending time on the daily tredmill. The reward for grinding alts seems to be "legacy level" which currently has no bennifit other than "unlocking" the "privilage" to throw my cash away.
