To get to the point, I think it will be a good idea to let people name their sanctuaries, and if possible, even add descriptions to the sanctuary.
This will allow for better coordination within the alliance.
For example someone can name a sanctuary “Ardentismaxima” and add the components into the description.
Or “Alliance Prefferences” and add the voted creatures in the description.
That will hopefully prevent people from adding irrelevant creatures (looking at you Velociraptor and Dracorex G2) into focused sanctuaries, and ruin it for everyone in the alliance.
Just a thought!
