I don't the mind of the change of how RDM plays. Well more like RDM being it's own unique play of the job since it is a hybrid. Looking back other RDM, from it's animations to attacking, it felt like this is the RDM it should be. In a way it make sense to this concept that the team created.

After seeing the video and what they presented on how the job will play, I kept thinking that the melee attacks will be the enders of the combo rotation. Again looking back from other FF titles, it was the magic that was the offense/defense/healing and the weapon was just meh other than stat bonuses. So I'm going to presume that the melee abilities will have some sort of debuff to the enemy or buff to you in some way.
