I don't know about you, but after 6 years of seeing people stand around the middle of the field in WSG contributing absolutely nothing to the match or someone on the Horde capping Snowfall, I'm getting pretty sick and tired of people having no consequences for making others experience worse because they feel like being cancer.
In a raid if someone is bringing everyone down you can kick them. In 5 mans if someone isn't pulling their weight, you can kick them. However in BGs, you have someone who is actually doing so poorly that it's helping the other team, there's nothing you can do about it. You can try to report them AFK, but that gets cleared as soon as they enter combat. Blizzard simply must implement a vote to kick feature for BGs. Sure Rated Bgs are coming soon, but people will still pug. You might say, "Oh but it will just get abused by the trolls and jerks or elitists!" That happens in every form of group play but why would anyone with a single brain cell want to gimp their group?
Not to mention, that loud mouth Ret Paladin (insert any overplayed dps) yelling at people for not healing him as he tries to solo the stables? Yeah kick him too.
