Guild "Romo" on Andorhal Realm

So, apparently on some Realms there are entire guilds who get off on griefing other players. Here's one that doesn't seem to behave in any kind of respectful manner when picking up non-guildies for dungeon pick up groups.

Here's one from the Andorhal realm:

One thing I've learned about :

Don't do an instance run with them when you're the only one not in .

They'll speak english to ask you to join, they'll speak english if there's more than one person not in their guild, but if you're the only one, they'll only speak spanish and roll need on EVERYTHING.
