Using CreateGroup without assigning an account entity will make title entity assigned and title will be the default Administrator of the generated Group. Then Entity API ListMembership can list all groups and roles for an entity. the question here, what's the downside for this approach "performance and limits for how many groups can be created that way"?
It is not recommended because as the player base increases, the group number will be large. ListMembership will return a large callback result, counted as Profile Read. Because 1KB of Profile Read will be metered as 1 “tick”, it may cost a lot if there is no restriction. Besides, if the callback data is too large, it will eventually return a timeout error due to RESTful API nature of PlayFab.
It is a bad idea indeed. So we heard awhile back about a new feature regarding "Group Search". any idea if this feature will be available at all this year?
Please keep track of the roadmap update, and you may send a thread on the feature reuqest forum -- https://community.playfab.com/spaces/24/index.html?sort=votes
