Guild Wars 2

Guilds are account based. If your Guardian joins [ABC] and your Warrior joins [XYZ] you can represent your Guardian on [XYZ] if you choose. I’m not sure if the guild panel shows your toon name or your account name. I know it shows if you are representing or not, but I’m level 40 with no guild, so I’m not 100% sure.

Guilds are accound wide and you can have 5 of them if i’m not wrong. And for every character you have to invidually set which one guild are represented when you play.

So you can have char X that constantly represent guild XYZ and char A who represent guild ABC.

But when on other character your guildies from other guild would see your alt name + account name and info you are not representing at the moment.

You can select invisible as your status in friends window. For others it will show like you are offline. The problem is nobody can whisper to you, or invite you to party(you must initiate whisper and join). And status will show you are offline in both guilds.
