All 4 One Event

It only take a few hours from 1 -> 100.
Let say you can only play 1 hour per day, you still have 50+ hours to train 3 characters.
That is more than 16 hours per character and that should be far more than enough to only get to 100.

Everyone have life, it's all about time management.

I think you're forgetting to add "It only takes a few hours to get to 1 -> 100 if you are (somewhat) funded".

Not everyone is.

I'm funded on my bishop, but takes me longer than a few hours to level non-mage characters to level 100.
