the mod i mostly waiting for is a static mod. no scaled enemies and items (or maybe reduced the levelscaling to 20%). splitting the whole world into levelzones. i know this make the open world more linear, i hate levelscaling so much that i can live with more lineary in the game when the higher level zones still are accessable at lower levels (what is more dangerous). companions should scale to the level of the player.
at best example would be the Oblivion TC "Nehrim" in this TC is everything static and in a levelzone.
is somewhere working on such mod?
