I think mobs in general are too weak, it's kind of insane we'd need to fight +20 mobs just to have a challenge, and how you can solo mobs up to like +6/(and +10 on certain jobs at certain levels) :/ You also shouldn't be able to duo a +10. So before they go adjusting Sp gains, I'd rather they adjust mobs difficulties to actually be difficult, and maybe then they can adjust SP.
