Here is my idea.

Why should we stick to just arlor. There should be new region and every region should have a story/quest line which connects them to other regions.

If sts starts creating a new region now it will probably take them around 6 months and ofcourse future quest shouldnt be like the orcslaying quest

I agree with candy's idea about scaling the old elites with the new cap and loot table should be refreshed
