SE made this game AST only, why?

That's on the players for thinking that the meta they formed is the only true way to play the game and try to force the developer to conform to their ideals. In reality, it's very much the opposite. The healer/tank issue is mainly only a western "problem." Likewise, (unsure about the east on this) people complained that tanks and healers were basically the same with very little in difference other than how much DPS they could contribute. From the changes, that's not what SE intended and is trying to brute force their intentions.

It'll fall on deaf ears.

How is this our fault? We simply adjust based on the functionality surrounding their game design. Why am I going to spend more time in tank stance when I won't have any need of it? Why am I going to heal using Cure when Regen is vastly superior? The devs can push back all they fancy. All it accomplishes is outright rejection from the playerbase. People have been saying for two years now Paladin needed magic mitigation yet the devs insisted otherwise. Lo and behold, Paladin falls out of use relative to Dark Knight and suddenly they slap magic mitigation on it. Healers aren't just going to suddenly use Cure and Cure II more frequently because the devs prefer that nor will tanks stay in tank stance longer unless its required.

Beating Scholar DPS, and White Mage in general, into the ground won't stop either from DPSing if the fights don't demand more healing. They'll just do less than they once did.
