These new rules are pretty darn clear to me (with the exception of the "intentionally leaving" part, but another poster clarified that). And I think this is 46 pages of cultural freakout. Americans don't like ANYTHING that can be seen as restricting freedom of speech, even if no real restriction exists. We just like to over react because that's what Americans do.
For example. If I was running a PUG dungeon and I noticed the SMN wasn't using any DOTs, and I said to them "Hey summoner, use your dots lol" and the SMN responded with "Don't tell me how to play my job! Reported!" (This actually happened once, but it was the tank who told the SMN to use their dots.), I could guarantee you nothing would happen to me. Because the GM would look at the chat logs and see I wasn't being snarky or antagonistic. If I had said something along the lines of what you would see in WoW or LoL, then yes, I'd get in trouble. And rightfully so.
There is a clear distinction here.
