I'm a tank. I fully expected a tank and healer this expansion, however when I saw gunbreaker announced I started wondering. Are they gonna add a healer or ranged dps? There are only 2 rdps after all. So deciding on dancer being rdps makes full sense to me.
I agree and would've prefered that resources were spend on preparing to release a full healer mid-expansion instead of doing limited jobs like blue mage. Like they did ninja. Then again, game development is a constant battle of priorities and risks.

You can't always do everything to please everyone at the same time. So I definitely understand that they are struggling to get things right. I hope you don't quit the game over something like this but I understand healers wanting more options, same way as I'm happy to get another tank. It's nice to read a post like this that can bring up concerns and disagreements without being a wall of text of rage.
