Yes, I'm aware. But, some players just aren't as skilled as others. Some players prefer a safer route. I don't mind as long as they contribute and don't place a burden on the rest of the team. I personally hate dying in any part of the game. A player on the ledge or cliff in everything he mentioned except for Phogoth contributes more damage to the boss and takes less from adds than the guy running around with a shotgun. If people want everyone to play to their style only, they should bring their like minded friends.
