4th class transfer (99+) for all sublcasses

It has been 10ish years since the GoD, may be it's time to open 4th class transfer for the other two subclasses?


Furthermore it could be even as:
1st two classes(main+dual) share some skills (of course you'd have to do a gigantic quest for that) and last 2 subclasses(with max lvl extended to 99+ like dual right now) could share some skills between themselves.


But regardless of the skill sharing suggestion, it would be nice to at least be able to level up all subclasses like dual classes to 99+lvl.
