I enjoy both solo and group play, its a good way to pass the time. I also agree that to an extent D3 is an easy game. Blizzard has Leaderboards for both Solo and Group pushes to accommodate all types of play
so your post is confusing, You find the same items, same quests, same bosses, same rifts, and same RNG no matter if you play group or Solo. The only difference happens to be the small boost to XP, MF, and Gold Find you get in a group. unless you think you need to be able to solo the same Grift as the you would in a top tier Group.
Also your post showed some aggression to "Elitists" saying the game requires no skill, but in all honesty it takes practice and proper planning to do what they do. You're making a generalization based off of aggression. There was no point in that part of your post except to anger a small community of gamers. If you don't like group play don't take your frustrations out on people who do, just solo and be happy for the great experiences you've had playing diablo.
