How many skills is too many?

[Felis]

Then, the change job system needs something simple, I actually had to bind each armor set to a slot of an hotbar, using three of them for all the jobs/crafting/gathering jobs we have. It is a waste and the only other option is do it manually passing thru' the caracter window, and that is quite an annoyance when you switch job often.

Use on every character 3 slots for one class from each disciple (except the disciple of the current class)
Then fill up the other slots on DoW jobs with the other DoW jobs, on DoM jobs with other DoM jobs and so on.
Now you can switch to every class with just switching first to a class of the same disciple.
