Good or no good?

But don't forget that a tank is primarily a "support" class, in a sense. Your role is to control the battlefield and ensure your party can do their job.

I also want to point out that a healer is just as much as a support job as tank is. As for dps, tanks need to do dps in order to do their job. It's essentially a requirement for enmity generation, so dps helps a tank fulfill their job. A healer's job is to keep the party alive by healing and removing debuffs when possible, which means their job doesn't require dps to be done. Of course, this is nitpicking and ideally both jobs should be doing dps. But to say that tanks should reduce their dps to allow a healer to dps more often is counter-productive.

Again, this could be solved by simply adding STR or some sort of damage mitigation to tank accessories. Right now, tanks are the only job that require multiple stats to be effective (stats that currently do not both exist on the same accessories).
