This is likely going to cause some problems with the whole cross-server dino transfer thing. Like people have stated there are tribes with no other purpose than to move on to a server and burn it to the ground. Now, that problem is worse. A big tribe can pack a few heavy transport dinos with everything they need to build a massive base right off, throw it up and start wrecking everything around them.
Well, I think I'll stick with extinction servers. There's no need to worry about a tribe becoming so big they push everyone off the server, covering the map in turrets and the like.
