I was thinking it could be really cool to have offline missions or quests you could do for stat increases or maybe training points. It would add some interesting rp I believe and I think it would help with those who have busier lives and can't be on as often as other people. Here you might say to yourself "Well, you can always afk self train or meditate." which is true but some people may share a computer, while others may not have a stable internet connection all the time, and sometimes servers just like to punt people.
Now for missions or whatever you wish to call them, I was thinking something like before you go to log you could either talk to an npc(s) or select an option under the channels tab (this would be up to you guys to decide) and choose, for example, "Deliver the Milk". Just like in Dragon Ball where Master Roshi had Krillin and Goku deliver milk each morning as part of their training. For that mission it would be a two hour timer before you would receive your training points or stat gains or however you choose to do it. You could even expand upon it if you wanted where selecting "Deliver the Milk" brought up options to do so without weights or wearing different increments of weights but would increase your chance of possibly failing your mission which would give you less then if you succeeded.
Interesting idea. We do plan to add some quests, even a story if we get to it :D
