But then you won't have any truly interesting PvP. The purpose of grouping up and communicating in PvP is too increase the number of fights you can take part in. When you PuG things if you're not dominating there's only two options, either you fight close enough to the rezpad so the respawn speed makes up for the inferiority, either you give up because a PuG team is bound to repeat again and again the same thing without any lead.
When you are in a team with like minded PvPers you can fight away from the rezpad (which in itself is a huge improvement of PvP quality) and you can fight uphill battles by constantly trying new things. Inferiority feels less hopeless.
You don't have to be an organiser really. Exactly like PvE, there will always only be a few guys organising and leading and the rest just following. Having a good organisation in PvE increases the guilds efficience. When players start showing up on time for raids, all come on TS without having to be asked ten times to do so, and listen to the raid lead, everyone has a much better time than when they have to wait 30 minuts for everyone to arrive, then an other half an hour for players to get some slackers on TS and then wait an other thirty minuts for the raid leader to explain tactics for the tenth time to the last logged on TS.
It's exactly the same with PvP. AFKers are a pain all the same, people not on TS or watching TV at the same time are a pain aswell and so on.
