Guys, maybe you should consider solo PvE something like Albion Online has some smaller expeditions for 1 player where he/she can get much better items but still not the best ones like in raids.
Or maybe just do PUGS. know your community get mostly good people in your raid and you are still going to progress with or without your guild . slowly but surely. Point of the MMORPG is that is MASSIVE MULTIPLAYER ONLINE so connecting with people, making friendships and enemies is a big part of it and a must. doing solo content is just not meant for these kind of games I think. Making PUGS is a real nice way to meet new people independently from your guild. Also if your guild is raiding at a certain time which is not ok with you, just change your guild. you have free will to do anything in this virtual world.
