They're ahead mostly because they rushed and started early. But yes the unintentional reset is sad, but it doesn't happen all the time so I can live with it.
I certainly won't mind if that weekly cap is changed to a lifetime cap based on the date when the player earned his first Mythology tomestone. Have the cap increased like the way Leve Allowances increase. This way I'm don't feel pressured to farm a fixed number of runs each week. I can take a weekend off and slowly catch up in the next two or three weeks, and end up in the same situation as if there was a weekly cap and I cap it each week. Once I earned enough tomes to drop that cap to 0, I have to wait for the next increase to earn more.
The leve allowance technology is there already, so this is entirely possible. IMO that will be a great quality of life improvement.
