Subclasses are active by default

I had an earlier post complaining that my client's hp doesn't match my server's due to wrangler hp addition
it turned out like 4 more subclasses are active by default also.

How do i deactivate them?
If anyone got a guide for a full working subclass system .... I would appreciate it
Cuz the one in the source am working on is complex as eff!

you save all the subclasses at your db, once someone login you switch off from every subclass, once they activate it with the packet you activate it and match there current hp with the new hp
and nope there is no guide for common sense but there is tons of guides on programming out there
