When did things change? Like ten years ago, I remember people would get really excited about the prospect of getting in a large group of people and doing something together when they reached max level. Now everyone seems to want to play alone or in small groups only.
The big question is, what diminished the raiding in this game? Was it marginalizing the loot or just the state of MMOs these days? Why do people prefer to play a online multiplayer game mostly alone or with maybe just 2-3 other people? If you can get the best gear just by farming alone, it's quite a lonely game.

It's not even really a time-constraint issue when the main raid can be done in one night over maybe two or three hours! Even that is "too much" for most people to consider doing, while 8hr atma farm fests are perfectly fine time wise.
Older MMO players like me don't understand... lol
