Sorry I haven't been on in 3 days...
but here's a suggestion
I have played about 30 different online games and this is an event which most of them have hide and seek
one player hides for example Slayer or Shadow (preferably:D ) and the guild members have to find them. We can make it in one map or all of cabal but my suggestion to make it fair would be to have the chosen player hide in either Bloody Ice, Desert Scream or Green Despair.
Seems like a challenge as well because the chosen player can be anywhere in any of those three maps.
The prize for this event doesn't have to be that great maybe just some adept stuff or Upgrade cores.
But I'd suggest having this event often preferably once every 2 weeks.
That way the guild members will be more active.
The timing of this event should be an announced timing such as every Friday at 7:00 pm not random times or random days (this is just an example)
It's a start...
Good Luck with this event and if you guys decide to keep it I'm the one you can ask for any answers or support
PS if u need suggestions for more events I got plenty of ideas which I'll gladly post
