I used to raid alot back the first game but when the second game came out my clan members gradually lost interest in the game and eventually I became a solo player, I haven't raided since and to be honest I couldn't be happier, I don't feel like I have to chase everything in the game. Besides you can get some raid loot as a solo player, the Last Wish has the wall of wishes that lets you warp to other points in the raids where you can pick up the chests and you can get spoils to buy some of the old exotic weapons with as well.
