Now, personally, I dont like 8th ed very much due to all the random moves and what-have-you and I haven't even played it that much, but I think that the rules are very well written and thought through. At no stage did I need to check and FAQ or check online for the answers. That isnt to say that there isnt a need for them, just that none of the questions that came up yesterday needed them.
I have no problem answering questions or providing a ruling if I am running an event, sometimes it is good to have a third party around to avoid things getting too heated. At the same time, I wasnt actually needed to answer the questions that came up, they could have been dealt with very easily, if people had just read the rules themselves.
So, I recommend that players ensure that they have a copy of the rules in some form, take the time to read them, and even if you cant remember all of them (since even the best of us cant remember all the rules for all the games we play all the time), try to remember where in the book rules can be found when they are needed. After all, if I do manage to get a game in myself, I would like to be able to enjoy it in peace.
