On Excel I don't find it too difficult. Quite few people already have this down, and it doesn't seem to take long to get new players up to speed with some basic info. On quieter servers, I'd imagine it would be more difficult as I think people who are exclusive to those servers aren't as familiar. Running a new event like this with a lot of new people can be taxing. But I find if you script out your instructions, and perhaps announce them in the request channel, it might help.
I don't know that I'd be up for changes to the current mechanics if that time can be spent on fleshing out the zone more. Maybe new secret rooms, more maps, and so forth.
