vertical progression.

I'm not trying to make some poignant point here, but when a dungeon drops i60 gear. and points are
used to get i70 gear. What happens when the next step up of dungeons are added? they drop i70 and
it makes those tomes redundant.

Hopefully this can be alleviated a bit in the future after a cap raise and they can start adding several
best sets, that are best for different reasons.
