Honestly, I will never understand the rage at forced group content in any MMO. The whole multi-player bit?..yeah its in the name of the genre. If you don't require grouping, whether through requiring specific party size or through difficulty, then you end up with no community. I know this because I played SWTOR.

I'm sorry that you're upset about being required to group up for a quest, but you don't get to save the world solo, it takes some help! Shouting in Gridania will likely never get you anywhere. Pop over to Ul'dah (which is the central hub on every server) as others have said and look for people there. I've no doubt you'll find some willing to go with you for just about anything. If you're adamant that you don't want to group up, then frankly, this MMO just isn't for you. You're going to run into the same problem time and time again. There's plenty of solo content, but the more epic content you need a party of 4-8 for.

Best of luck!
