bonus

I agree. It doesn't have to be anything too flashy, maybe gold and/or certain items/equipment?

 

Should just be only gold. If equipment, players wouldn't need to hunt for them and the excitement level of this game would decrease. IMO though

 

Maybe if you play for a month without missing a day, you could get 1 crystal or 10 nobility points or 3 infernos or 3 aquas. That would appeal to constant players and new people too
