I have to agree with another commenter. Making a solo mode would defeat the purpose of Raids. I understand you point, I don't raid much because I don't have the correct builds or gear or whatnot, but you also need to understand that having those things are kinda essential. Raids are tough, especially when learning. That's the point though, Anet wanted it to be tough, challenging endgame content. Get out there, make some new friends, you are playing an MMO for Dwayna's sake. Plus you can always read the story on the wiki or look up youtube videos of it.
