I love the concept of this system (the armory system) and it was something I was going to make a thread about myself. So I'm glad someone else took the initiative.

Classes aren't roles, they are simply a means to an end.

I think one of the issues is that SE has not fostered our ability to make our own roles. So although we should be able to make a BLM or THF, we can't do so under the current system. Similarly, if the role you want to play requires high lvl THM and, say, MAR abilities, then how viable is this system in giving us freedom if it makes us rank up both classes simply in order to fulfill our dream of playing that particular role?
