I'm not saying that abuse doesn't happen, but I wouldn't consider it a common occurrence. I've been playing since 1.0 and I've never been vote kicked from anything. I realize that my experience alone does not dictate how the entire player base experiences it, but neither does yours. I can only assume that if it's happening to you on a regular basis, there must be a trend with your behavior. People don't go into duties with a mindset of needing to replace someone. No one wants to wait around for that. I've had plenty of experiences where a party member is essentially dead weight, but we carry on and just complete the duty.
