This is a leveling guide from dulfy that I've been using:
Daggerfall Covenant
Stros M’kai & Betnikh (starter)
Glenumbra (5-15)
Stormhaven (16-23)
Rivenspire (25-30)
Alik’r Desert (31-37)
Bangkorai (37-43)
I am currently in Rivenspire at at level 28. Once I hit level 30, even if there are more quests to do, does it make sense to progress the main story line to the Alik'r Desert at this point? Or do I need to keep grinding out the quests for the XP so I can maximize my XP and reach the VR ranks after completing everything in Coldharbour? Basically I'm asking if it's ok to skip quests and move along to the next area once I achieve the specific level.
