Yes what this man said you have to play PvE aberration alot and use it as main to understand how it is!
I've got about 500 hours on this PVE Abberation Server. I always ask for a flying Rex with laser eyes, but noone gives me that.
Well, seriously, in my opinion the only reasons for a teleporter would be
- transporting Megalos, Spinos and red gems from red to green area or vice versa
- transporting your dinos from low ground to high ground or vice versa
And you can already do that by walking. It just takes a little more time. Also you can fly with rock drakes and transport dinos with crabs.
It's just a comfort feature, and it's not really necessary.
The 10x material gathering, and some OP mods like steampunk lead to some sort of gigantism and lazyness. And sometimes, one forgets to play the game as it's meant to be played. The idea was to include challenges like pathfinding or dealing with dangers like the nameless to give people the feeling that it's a survival game and not a sandbox building game with dinos.
