I personally think that sidequests should yield SP and EXP. I don't care if the loots/rewards are omitted but SE shouldn't omit the SP and EXP gains. It doesn't have to be big gains but atleast a small marginal gain is good enough. I mean I would rather get 20 SP and 30 EXP per mob on any sidequests I do instead of getting a stupid "leather trousers" that I can buy for a decent price.
