There is Longer kinda content that requires groups.

Like FFXI had relic and relic weapons for dynamis. Sure causal players can get relic gear but the very hardcore will be getting a relic weapon.

Adding in 30min fight as a full amount of content doesn't help the game. There needs to be longer content period... and longer waiting periods to do them.

Right now the game is in a werid period where its still in development and cant focus on large base content. I dont see any real content coming until after 2.0. If they add anything large now they would have to do more work for them to readjust it after 2.0.
