What I'd like to see is a GM event where the GM's don't take control of the NPCs. I'm curious, if they appeared to just be a normal player and acted the same way they do in a GM event would anyone take them seriously and do it?
But for the most part I don't like GM events for the sole fact that they attract everyone so there's massive lag, channel activity and non-RPers. I know we've had threads on this, and I try not to discriminate against people who are new to RP or just joined the game so don't know better. Whenever I meet someone like this in game I usually try to teach them the ropes, and send them on their way (assuming they're willing) but you can't do this during a GM event because there's not only too many of them, but we're trying to play the event so there's not enough time.
That's why I'd like to see the GMs start a plot, but for the most part the ordinary players will play it out with GMs reappearing every so often. When the GMs are always present, it often turns hectic.
