I did it^^ All by marks and exotic bounties/Xur (I never got a Legendary engram that was for my class^^) I now have a Legendary or higher in every slot. I am going to take on the raid (Maybe Tuesday so I have a full week to get through it?), but have a question for you raid vets; I want to go in blind (no one in my group has done it yet) because I thought it would be cool to figure it out together on the fly, but most of us only get two hours or less a day to game, so spending it all getting stuck in one place sounds awwwwwwwwwful. But figuring it out on our own sounds fun. I am conflicted, as you see, about how we should approach it. Is it worth going in blind? Is there a section or two that are "must research before hand" in order to reduce frustration?
Honestly, it's full of sections like that. It's fun for the first time, but its even more fun if you actually know what you are doing. I'd hate to go in blind and not have someone to guide me.
