Who cares what other people want or do? If you have a group, good on you go out there and take Riven down. Don't be mad at other people that want or expect other like minded people to play with. If I'm out on a time crunch and want to knock it out fast I sure as hell don't want some noob stumbling about making it take much longer than it needs to. There are groups for all players. The elite will be elite and continue to be so, the inexperienced players like you will always be offended by such group requirements because you don't meet them. In the end it up to the player to gain the experienced needed. There are plenty of people out there, yet it always seems to be the inexperienced players attacking the experienced players for their "requirements" to join their groups. They somehow feel entitled based on past experiences (like you obviously do) or think that just because the other players are much higher level with more experience that they should carry them through the raid. That's not how it works, go put the time in yourself and gain that experience.
