Its clearly obvious you have no clue as to what you are talking about and your argument is paper thin and ill tell you why:
You are assuming you have any idea how hard dragons will be at level 4. You have no clue how hard it was. It could have been so hard one player died after trying his best and failing resulting in the save revert we heard about.
If it was numerically possible to beat a dragon at level 4 then they're too easy, even on the easiest difficulty.
If the entire main quest is level scaled then that's a little better, but will still be VERY immersion breaking when the dragons you fight in the main quest are 100x easier than the ones roaming the mountains.
If you can get through the main quest without ever killing a dragon or anything similar that's kinda lame, but I guess I can live with that.
