So my wife and I really like DDO. We mostly play by ourselves and have built a guild for us and just in case any of our friends want to join us. We've even gotten our airship and several airship rooms. We enjoy it as a symbol of stuff we work for and using it as a kind of "housing" for us. So we arent looking to join other guilds.
But, we would also like to eventually do the bigger group things and raids. We'd love to make some friends with other people who regularly do group stuff or perhaps make friends with some guilds who may look for others outside their guild to join their raids (casually).
I own every adventure pack and expansion and she is VIP and currently has the ravenloft expansion but we will be getting her the others. We are only level 11 on our new "mains" right now.
