You know... Some people enjoy crafting and gathering.

I had a friend who literally stopped leveling so he could do more stuff gathering and crafting and playing the market. And believe it or not, a lot of people enjoy the socializing aspect of the game more than leveling.

So they will level very, very slowly (but consistently). Also, you have to take the amount of new players coming into the game and the amount of old players quitting. Some people are level 50 - did coil - no longer playing. Or level 50 - game is boring - quit. Both entering and exiting the game puts the average player at a lower level.

I would say that 30ish is not an unreasonable estimate. I still see people spaming asking for Stone Vigil.
