In some mmorpg's like wow (sry if that's against the rules), they have a rested xp system, or a bonus pool. Basicly what it is, is when you're offline you charge up your rested xp. And while you have rested xp, you get double the amount of xp you normally get. And as you train your rested xp decreases. This is so that people who don't play everyday can still keep up with those who do. Will this be implemented in the game?
I'm not sure I explained it verry well, I just hope you guys are familiar with the concept.
