It sounds good but I foresee this being another flavor of the month map mode.
small tribes has a 24? hour timer before you can recruit someone else. conquest every big tribe had log out rooms and no penalty so they could fill slots and maintain mega tribes. There needs to be that small tribes penalty.
no cliff platforms. Thats the one Item I would include to open up building in different locations.
caves need to be blocked from being built inside, or increase the damage in caves even more.
disable 'Note Runs" I was lvl 70 twice in a matter of minutes on ARKpocalypse last night. Force people to work the early levels.
ban streamers using .ini on twitch
and rhinos will be the ground meta, especially if weapon damage is reduced.
