They're there just in case you feel like going out and grind. Keep in mind that since it's an RPG, exploring and getting to know new areas all alone it's quite cool.
Well at least that's my point of view, and that's what I do on every RPG I play. For example, on a game like TES IV: Oblivion, I used to wander around alone without using the map for hours and hours, just to see what's out there, and what I'll find. ^^
Please give more xp bonus(and more drop bonus) beacause i need my marks to be 50 as soon as possible
