Neo city question

Does the quest supposed to be repeatable? because i can do them every time i finish them (Not talking about andy's quests)

Yes, those extra quests are intended to be repeatable.

They're completely optional and have nothing to do with the main quests; they're only there for extra exp. Think of them as a bonus, if you're training in those maps.

It amounts to very significant amounts if you keep repeating the easy ones actually (500k for killing 50 monsters and/or a boss), but after some testing I find that it's as good as abusing the system, so I stopped.

If you have multple bonus EXP sources e.g. 2X, 1.3X, 1.5X cards, then don't bother. Grinding gives way more EXP.
