Not really sure who all is in your guild or all was there, I know a few names but it doesn't really matter.
Today you decided to grief a Company raid on Baron. I know this is a PvP server and that's fine. Up to this point we'd always had a reasonably considerate relationship between guards and defiant. We generally let you participate in invasions, especially bosses, so long as you didn't attack us. That's right I said "LET you." Any guard who's been around a while knows 90% of the time PvP starts during an invasion the guards lose horribly. Why? Because we outnumber you.
What you did today (Yoona, Spatula, Mathi, The Other Guys who were there) has unfortunately for you put your guild on Company's KoS list. No more leaving you alone when your afk. No more letting you participate in invasions. No more not ganking you. That was not "friendly PvP" it was outright griefing. Also, expect to be spawn camped, a LOT (something I have not done to anyone, yet).
Hiding in the river of souls until we started baron so you could come out, silence and attack healers is not PvP, that is griefing.
Hopefully the rest of the server can maintain the relatively civil, considerate, friendly, atmosphere we've enjoyed to date.
