I've been asking for this for years too. This is a problem that just gets worse with time, not because of skill culling but because of the proportions of older content vs current level content. At this point we have probably 10% of the content in the game actually at max level. Everything else is synced down and plays like crap because of it. It kind of defeats the purpose of leveling a job when all you're doing with it is synced content.
