(2) How can we get rid of the confusion that seems to accompany these events?
I think many issues can be solved by using 'event guilds'. In case of 'good' vs 'bad' guys, those two groups can be represented by two guilds which can be created for the event (in the case of the Gugrontid take over, it could have been 'Thugs' versus 'Gugrontid Defenders', for example). Anyone who wants to take part in the player event can join the corresponding side. The two groups can be organised by two group leaders, including muting people who annoy with spamming or even kicking them if they are just nuisiances and no support for the event. Fighting, too, is easier, because it is simply done by starting a guild war. No more auto-accept problems and 'who challenges who' problems. If it is required to sort things out, the guild war can be interrupted and all the fighting would stop immediately. It would also be helpful to make the guilds public, so everyone is able to recognise an enemy instantly.
The only drawbacks I see at the moment:
- participants who are already in a guild have to arrange the comebackto their guilds (when the event is over)
- communication is only possible within the guild, so an overall group with the two guild is still necessary
