Does a new guild have to follow raid rotation rules?

[purpherb]

Just wondering, I am not asking because I am against it just wanna know what's up. I watched a few of the sirken twitch streams and in that he kept saying how he wants everything to be ran by the players (in regards to raiding) like it was on live. I also know that rogean is a stickler for classic details. Would a new guild have to listen to the class r and class c stuff or could they just ignore it if they choose to. And if they have to follow it, why is it like that, just to stop griefing? What would happen if a new guild just told all the other guilds to F off and they're gonna do their own thing. Would the gms ban them or take away their loot?
