If you don't like the job changes like I do, then refund your Dawntrail pre-orders. Send a message to the team that we are not happy with the changes being made to FFXIV's combat.
If I could not pay for later expansions and keep playing the older versions of these jobs I would but sadly CBU3 does not want to make legacy servers so I will just have to leave this game until it becomes better and I suggest you do the same!
