As you can see main quest is missing between Velia - begin Valencia main questline.

This means no gear, no upgrading.. No season XD help?

Same problem here, quested till Red Nose, got boosted to 56, did succesion and now the Valencia Questline starts.. I don't remember if I took the Aulustin Simpleyfied main (Groth) quest, but don't see that in my questlog. And I don't see the older main quests? 

If you don't see any quests before Valencia in your Quest log, you have accepted the simplified quest from Alustin's daughter. Look in your Inventory for the book with the Fugar Quest, Right-click the book, accept the quest, it will complete according to your reached levels. Call the black spirit, turn it in and find the new book in your inventory. Rinse and repeat. You WILL get all the Season Pass rewards, but there is a bug that is preventing the last chapter Fugar quest to complete it I heard, it will be fixed next maintenance.

NB: You will get the inventory slots and enhancement stones and stuff, but less when you would be getting in the main quest line. 

But you will skip the main questline till Valencia/Drieghan completely and still get the necessary rewards to be up and running with this char.

Man this is such a drag... I got the simplified but my buddy didn't so we can't easily quest together as we level here. He's very much new to this game so trying to teach him stuff would be easier if we were on teh same questline :(

nothig is less... you take all the inventory and stones.... and SP.
