hey, i started the game 2 weeks ago and i am 4k CP now too. The North Mediah Content became much more enjoyable after you ascend your class on level 60.
But yeah the 7000 CP zone is just a zone so the 6k+ CP people have something to do. But i was there with 4k CP too, picked 1 monster and killed them one by one for the 1 AP knowledge, its doable if you fight them one by one ^^
that map was made for whales pepz. its free to explore and drop dead lol
