There is absolutely no reason for the tome cap even to exist in the first place. So what I want to farm 24/7 and gear all of my roles with BiS that has actually no 'real' value beyond fun and doing the fights using different roles.

How is it different from logging in 1 day/ week vs being active and not logging in after for a time? I would very much like the developer not to treat me like a child who needs their hand constantly being held and told what I am and not allowed to do with my own damn time and money.
