Problem with this is that pvp strats change, so do burst rotations and not all tanks control the same. They can't be constantly updating the pvp training to account for changing tactics.

E.G. chasing healers isn't really a thing anymore, they kind of just stand there and take it. A MCH bursts things down in a matter of seconds and then is useless for 3 mins, while a MNK is more about constant damage and harassment. PLD focuses more on stun locking single targets while DRK is more about AoE bind and heavy, WAR tends to clear out crowds with knockback and drag back single targets trying to run.

It would be hard to make the training accommodate all jobs and possible tactics now and in the future.
