Its a bit unfair to release new jobs based upon research into the current battle system which is about to be changed.

With the upcoming changes to the battle system, cross classing and the visual UI, which could end up being as impactful as being a New Game +, you may well find players changing their specialisms.

For example with easier visual UI you may well find a lot of controller players more willing to play stressful tank or healers roles if they can visualise and be as quick as players with mouse over macros.
