So you want to punish all the players who play DPS, just to prove a point to SE?
What you're suggesting will just split the community up even more than it already is.

That said, I DO agree that it is unfair that there will be no new tank and healer classes in Stormblood. I just don't think this is the way to do it. You are simply punishing other players who will just grow to hate tank-players because of it.

Showing dissatisfaction towards the lack of new tank and healer classes can be shown through feedback. There are many who are on your side on this, and together we can make sure SE knows about our opinions on this.
