I have no problem with this. I run b spec when I go to class to gain some xp when im out. Eventually I shall complete the grind and have completed everything in b spec. That is my goal..
Gain XP for what purpose? I guess if your out then your guy could be driving for you to get money for cars etc, i get that....but isnt it just plain crazy that this is what GT5 has become? grinding away to unlock things that you prob dont actually need to have fun. wait.... this sounds kinda like everyday life!
