I'll give it a 2nd thought, I guess. I personally hate "pre-booked" events a lot unless it's the once-in-awhile large events since it compensates a lot of flexibility and my real life schedule too...
It just didn't really work out well the first few times. All we got is to arrive at the conclusion that either we are spoonfeeding (regardless of the overall being negative exp, strangely), inefficient (waste of their precious exp time) or it's biased (GM help is interference for selective individuals) Since the comments back then were overall not very well liked, that's why we buried this in the past. We had some pretty not-so-pretty threads related to this in the past already. Since it's not a huge loss not to host these anymore while also listening to the majority of the opinions of players, we didn't host these anymore.
Should we try to revive this idea again and we end up in the same place, we will *not* give it a 3rd chance and will let the server majority's opinion decide if these will stay or die.
(I personally don't mind hosting these at all if I don't need to book in advance which sadly I do... since it's the only time a GM can 'do something' and feel like playing RO again while GMing all at once XD)
