a lot of the GW1 players don't like the fact that there is no Guild vs. Guild PvP. Here is the official answer to it:
http://www.tentonhammer.com/node/103799/page/3Ten Ton Hammer: Any sort of plans for Guild vs. Guild PvP?
Eric: No, that’s one thing that is a pretty big departure. The reason we didn’t want to do it is that even in guild vs. guild in Guild Wars 1, we found that what we had to do is create a lot of systems to circumvent that. It was just really hard to get that many people all from the same guild on at any given time.
What we’ve said instead is that our guilds are going to be about building social networks, and if there is a group of people that are the hardcore PvP guys they’re all going to be in the same guild anyway so that’s OK. And they’re going to register as a team, and be known as the team from a specific guild and build up a reputation. And then that gives them the flexibility that if they want to have a top team along with a team 2 and team 3, they can do that kind of thing. So we wanted to disassociate the two things.
Now in World vs. World there are things like guild keep claiming, so you will claim a keep that your world has conquered, and your guild can claim that and fly their banners, they can upgrade it, spend resources, and do all kinds of stuff.
We haven’t talked that much about our guild activities and things like that, but we want to have systems so guilds have reasons to play together, and we’ll talk about that once we have more of it developed. But guilds in our game are going to be all about social networking and giving them reasons to play together, but not forcing them to do anything.
its clearly a good decision if you ask me. If you want to play with 10 of your friends/guildies in PvP against 10 others, there is still:
Hot join play uses a game selection system similar to many FPS games which allows individuals or groups to join a game based on map, available space, and other settings. It will have variable team sizes which can be different per server so might be one versus one, five versus five or ten versus ten.
It was mentioned in an interview that players will be able to join the same server regularly, forming groups of players that frequently play together.
http://gw2.luna-atra.fr/interview_et...c_arenanet/#voLuna Atra: We would like to learn more about the PvP mode which will replace competitive GvG, what shape does it take and what are the aims on the maps (death match, take the flag …?). ArenaNet stated that, in order to make this competitive game mode a real e-sports, eight players was too great a number. Since I cannot imagine an effective competitive PvP with four players (and I cannot think about odd numbers) must we infer that the groups will be six players?
Jon Peters – Game Designer : Competitive PvP in Guild Wars 2 will take a few forms. There will be hot-joinable pick up play that will allow larger team sizes, as well as tournaments that have fixed sizes and times. We aren’t currently revealing the game formats, but there are a number of shared goals that we want our PvP game types to have. They should all be easy to join in the middle of play and scale well to different team sizes. They should be equally fun for casual and competitive play, with dynamic team-based objectives. They should be observer friendly and avoid stalemate situations. Most importantly, they should be FUN.
Many competitive sports and e-sports do use an odd or varying number of players. Soccer is played with 11 players per side, unless it is indoors and then it is played with six. Counterstrike uses five person teams for competitive play. We believe that in order to build a more cohesive user base for competitive PvP the team size for tournaments should be smaller than eight (to make it easier to form teams), and should remain consistent between all game types and tournaments ( to avoid fragmenting the user base). We are not yet revealing the actual team size, but it will be greater than four and less than six.
