The game does not let you harvest everything if you are solo. You can only harvest the 2 you selected. That does not preclude you from harvesting all types of resources though. As long as there is someone in your group who has the requisite skill to harvest something, and you have the proper tool with you, you are able to join in on the harvest. As long as your overall harvesting skill is high enough as well. For Tier 2 nodes you must have a base harvesting of 100, Tier 3 is 200 etc...
