Low level Combat gameplay and Job identity is HORRIBLE.

Because they would end up having to rebalance all of lower level content to contend with power creep. easier to make the leveling process faster to get people through the lower stuff than it would be to re do everything....again.

The dungeons were originally designed for far more abilties at their level than available now. And that happened without rebalancing all dungeons. Lower level balance is terrible, max level balance is far far better. On the other hand it's pretty trivial to scale down numbers from level 90 to anything intended for the level of the dungeon.
