While i wont join Shambala but do like to see people make a go of it. When im not grouped for other things i will sign up to help it pop for those who want it.
What i have seen work in the past for many pops is an event, even if it is small. Any items you have to offer that you could give as reward incentive (cos the main reason Shambala is laughed at is its reward incentive and people love rewards)
The winner screenshots their points and forwards the image to the Event handler and compiles either a list of names based from that to pick at random for a winner or can do an overall winner in set matches.
There are many types and ways you could organise such a thing, having themed events too.
Christmas might see more people here to join too, so maybe get something underway by then?
Also make a script to post and encourage others to join. I’ve seen it work from Nine Swords.
Perhaps discuss with them how best to go about it?
I know you didnt want to do an event but you can keep it simple and not involve too much work, the more people you have to help you with it the better.
