Better private league templates

Please allow us to mix & match leagues and mechanics, such as alternative ascendancies + idols + whatever else (3.18 Sentinels or Necropolis with graveyard crafting, please!). Void the leagues or whatever.

As it currently stands with the chosen templates, no one in my friend group is interested in playing because the things we want to do isn't available in the current templates.

Are private leagues usually not Voided? Seems strange to me. Like you say, if they are voided they don't have to worry about the migration and can have whatever people want in them.
