Then why play an MMO? The whole point is the fact that everyone in your party is controlled by a real player. If you just want to play alone, then you can get any RPG. The thing is, it doesn't encourage forming of parties one bit if the entire quest line is balanced for a single player soloing. Playing that quest line in a party makes it extremely boring. Which means that most MMO's these days are extremely boring compared to the old FFXI, which sucks.
Dude... if you don't have time and you're literally SITTING there, SPAMMING chat looking for a group for GOD knows how long... and you can't find one? Why would you want to pay to play for a game like that?
You can still have an amazing world and amazing elements for every type of player in it. I love MMO's. I just prefer to solo if I don't have a lot of time to play or when I know it will be hard finding a group for something.
