How would you feel if they scrapped the current "classes"?

I completely understand what you're saying. What I'm saying is we need to worry about advanced classes further down the line. I'm concerned with the original seven. I don't want a RoZ expansion already when we haven't fixed the original. Being able to unlock a RDM simply by leveling two jobs will not help the two jobs it's coming from. Why can't I just use Marauder and be unique? Why does it have to be a required tool in order for me to obtain say Berserker?

There is only one way I think you'll be able to do something along the lines of what you're coming from. A progression of the basic class to an "advanced" class could be achieved by slowly turning a job such as Gladiator, into a more defined role such as Paladin or Dark Knight. Here's how.

At some point down the line, let's say Rank 25 since it's in the half-way mark, you will be able to access a quest with your Rank 25 Gladiator that allows you to start training you Gladiator into a more defined role.(Again either Paladin or Dark Knight) This would go a long way into keeping the original seven classes unique since they will turn into more defined roles as either DD, Tank, Healer, Magic DD, Buffer, etc.

We would also need to keep the ability to cross abilities from only a certain other jobs, like you said. For one, I don't think we should swap DoW with DoM abilities. (Only exception would be the Paladin & Dark Knight options since they also require magic in certain ways.) This would be a far better ploy to go on than just leveling Gladiator, Thaumaturge, and whichever else you said to 30 and then leaving them high and dry. That would just make the original seven pointless to level since there's no incentive there to level them other than the fact that you'll have the same stuff on just another, more "advanced" class as you would say.

I think we are both looking at the same destination but approaching it from separate routes. Either way works. Basically creating a hybrid of two or more classes to create a more refined and specific job that executes the intended role more efficiently. You are saying to expand on the current system but make the new creation more specific in nature by unlocking other aspects of the main classes. I am seeing the current classes as "starter" classes to acquire the skills necessary to achieve the intended role by meeting the minimum requirements to serve that role.

As far as abandoning the initial classes I am not saying that at all. I am saying that you must level the initial classes to the minimum levels before being able to explore the job you want to explore. You would still be able to continue with the original classes and continue to add to that job skill pool by leveling the classes involved in making up that job. Keeping with that objective in mind, you would not be able to max out the job until you maxed out all of its comprising classes. Kind of a "tools of your profession" situation.

Your way works as well with the "evolution" method of advancing into a more specified field. You advance the first class to its prerequisite level and then choose an aspect of that class to define the role of that class while still maintaining the base of the class.
