Why the +/- Enmity stat needs to be abolished

[LaymanX]

To be honest I've never been a fan of the "I'll take all the hits because all the other classes can't" style of tank in the first place.
How it should work is, instead of tanks focusing on skills that direct all damage to them so the other players have nothing to worry about, they should mostly have skills that mitigate the damage the other players will take when they do get attacked. It's fine if the tank class has some skills that force the enemy to attack them but it shouldn't be based around it.

In other words enmity should essentially be abolished. That was part of the challenge of most of the other FF games: Sometimes party members you don't want to get attacked would get attacked.
