WHAT!!
So in other words, they are punishing early exploration again, this time by making it so that if you set out and explore all over the place early on, the game will be filled with meaningless pushover enemies when your character levels up. This is the first piece of bad news I have heard, and it is VERY bad news.
I want an Elder Scrolls game that does not punish exploration.
Fallout 3 did this and it worked pretty well, as I understand dungeons has upper and lower cap on enemies so low level dungeons is probably 1-8, medium level is 6-15, high level is 13-21, and 18-30
Now if you enter a dungeon at level 1 it will stay at level 1 however you will not stay level 1 forever only 1-2 dungeons and if you visit a medium dungeon it will lock at level 6.
My only concern is respawning, oblivion was to fast here, and Morrowind mostly had none respawning expect special areas where it was way to fast.
I might prefer that a previous visited dungeons you cleared out is repopulated after a couple of weeks with higher level enemies, but the map look like it should be big enough.
One weakness in fallout 3 was that it was better to farm spawn points than revisiting enemy bases, fast travel to the location for the nuke cola challenge, go north and get another gatling laser for spare parts as it was no other reliable ways to get it.
