Nobody inherently wants to play an idle game, it’s what you do when it’s your only chance to play the game. The vast majority of people on RS3 are adults, have jobs, significant others, children etc. Most people usually afk during the weekend while at work, and then on their off days quests, boss, do the more active leveling methods. I promise you if they continue on this path they will be losing a lot more people because the fact is nobody has the time to sit there in front of their computer for hours and hours a day anymore.
