You are able to do group content of FATEs low-level, and many Levequests can also be completed as a group starting at level 10. What I like about this game is it doesn't force you to do things in a group, but it doesn't restrict group participation if you want it (except in instanced story battles that are designed to have NPCs to assist you to accomplish objectives.) If you want required group participation, play FFXI, that's what made me dislike and quit that game.
