I have a private hunting T3 world that has a platform-like network of locations, but they are all on the ground (I called them Summoning Temples). Maybe that’s gonna be a good compromise for you? Warping between regions but staying on the ground? If not then just warp to one of them and then continue on foot around that world. It’s made of mostly flat terrain, no large water bodies, no ice and very little trees - so easy to do meteors (only setback is that I got those caves starting on surface and leading quite deep - some regions have them and those are a bit annoying; the temples I built in regions centers - 16 of them - I tried to place in cave-free areas).
It is a small world though so player limit is 10, meaning your hunt group can be maximum 10 people.
Anyways - feel free to take a look:
of course
thanks for pointing out - corrected
