PvP Question - Basics

I looked around the stickies but couldn't find the answer to these questions about PVP.

Currently I'm leveling a char in PvE. I haven't done any PvP other than the PreSearing battle before moving to the real world. So I have a few questions if someone wouldn't mind filling me since I'm not there yet:

1) What are the options in terms of how many people can battle at once (2 vs 2, 4 vs 4, or is it like 20 vs 20)?

2) How are teams currently chosen? For example, can a guild wage war on another guild and JUST those 2 guilds fight?

2a)If so what if one guild has twice as many people.

3)What if you aren't in a guild? Are there random "pickup battles".

4) Is there always 2 teams? or is it ever a FFA?

5) Does the battle field change in size, color, terrain, etc?

Feel free to add any other details...I'm a noob when it comes to PVP.

Thanks

THe most I know of is 6 teams of 8, which would be 48 people in a single battle.


There are different options. But yes, you can do GvG combat.


I assume they just get outnumbered, never tried it though.


Yes.


See first answer.


There are like 6 different PvP maps, I believe. So yes, it does change.

Thanks for the info!

holy crap......im scared.

I wish we could spec on some of those, must be chaos.
