This is from a post I found on another web site in regards to possible class job combinations(Idea`s). While I don`t agree with everything on this document there is many good ideas and a lot of work went into it.

IMHO FFXIV does need greater job diversification to help increase play styles and so that players are more attached to the Job/Class they play. I believe this may help ensure that the players try different set ups to beat fights as they have certain jobs/classes they wish to play.

I also like the idea of having advanced classes that have several requirements/great quest line to open them. I would think that these advanced jobs should start at level 1 and not the current method of the class/job being the same level.

I really like the idea of a long term quest, hopefully epic story line for them and it also brings players back to start leveling from 1 with new players, and gives new players something epic to aim for.
