Complaining that a lot of content is group focused in a mmo, is like complaining about people attacking you in a PvP game..

Now i love solo content in MMo's i do a lot of it as sometimes i just CBA with people or i want to just get on and not be waiting around. Their is loads of it in XIV now, ok not so much the Main GC stuff, or Dungeon stuff as that is the Group content.

But to save you further frustration:

Solo focus:
Main story, mini quests, Class quests, Crafting, Gathering, Exploration

Group focus:
Dungeons, Grand Company, Behest's, Caravan's, Hamlet's, Job Quests

Mix'd Focus:
Leve's, achivemnts, Gathering rare items

I could expand but that does cover it for the most part.
But I agree with others find a LS that suites you i have done those quests many many times since i completed them, for LS members, Friends of LS members and random people just asking when i have nothing else to do atm.
