They probably suck at it. My gang can take down any raid with six or less. People hate us because we maximize rewards by doing them in small groups and not helping low levels if we are pressed for time or just don't want to carry them.
Each time one of us reaches level 40, we throw a party involving dinner, drinks, and lures. No spoofing and no cheating in our group. If you're sucking, we'll let you know.
