Id vote no simply because Clericy is an adorable namehehe
Now Zynthar and I have something quite in common we both come from fairly large guilds on the same server its not that you cant develop a large group of friends or even run guild only. The thing is sometimes it dont work that way. Even in a big guild you get a period where your somewhere in the middle. People are either in the mood to run high levels or really low (korthos levels) and you maybe somewhere in between. So instead of waiting on the korthos guys to get up to your level you may form up or join a pug and meet new people. Or heck maybe just into pugging to find new recruits for your guild.
So in those scenarios yes you can still run into very bad pugs along with the good ones and its times like that where you really would love the options to boot people.
Though its still something that would be abused in my opinion so I could never agree to it being implemented.
