How would you feel is level caps were integrated with the Main Story quests?

I'm going to repeat myself here but since there's quite a few people against level caps for whatever their reason may be, how does everyone feel about level sync with enemies that scale to the parties level? OR a difficulty select option similar to the one we have for guild leves?

[edit]
Or since some people seem to want to be able to get through the content really quickly, what if there was simply just an option to have the enemies level scale up to that of the highest level party member? It could be as simple as giving the enemy more HP and strength to become more of a challenge for the party, and as I said it could be optional.

This way the party doesn't need to be level sync'd, only the enemy is scaling to some kind of medium in between the levels of the party members if they desire something more challenging.

Opinions?
