Started an LS with a group of people from FFXI When FFXIV came out had about 35 people at launch. Currently all but 2-3 of those people quit and there is rarely anyone one on the LS at the same time.
Which leads to me having to solo pretty much everything. I soloed Gladiator up to 50 because there was really nobody to play with. There in lies the problem with FFXIV. You can't really force group content on people when there are so few people to play with or get things done with. Forming an exp party is incredibly hard if you don't have a set group of players to play with.
After the first month or so of FFXIV most people I knew quit. That is the problem with FFXIV lack of players to do forced group content. I am hoping the new job quests are soloable or I won't be able to do them.
