Trollshaws have not that many of the quests, and lots of these are group quests ( giants, spiders related chains), so no, Trollshavs alone wont get you to level 40. You will have to supplement it with questing in other areas.

Thank you, Turbine, for listening and giving us an opt-out of FE! Good work!
