What most people agree on is that what made large tribes go underground are titans. So making something with them, like anti titan artillery will make playing possible.
But please remember that while now playing from caves is must have for everyone but the Extinction Mega tribes which run their titan 24/7, then for a smaller tribes being in a cave was just an strategic option to be able to stand against larger tribes.
I hear that many people scream about one man being able to defend a cave against larger tribe.. What is wrong with that? Without that option small tribe cannot defend against bigger at all. They still wont be able to destroy bigger tribe but at least wont get wiped.
I have 4k hours under my belt. I played in a no tame, in a mega tribe, but mostly I play solo on normal official pvp. And when i speak solo i don't mean trolling, and griefieng everyone around. But playing the GAME with taming breeding and doing bosses. I usually do not attack nor grief anyone and try to help fellow solos and smaller tribes. The only way it is possible for me is when i get my cave. And it is not only about choke points. I usually build in ragnarok dark cave where i can setup 100 turret tower to defend from the one dirction the attack is possible. And still I am affraid of mega tribes as I cant get enough ammo to get rid of soakers when I'm not online . C'est la Ark
Truth to be told is that cave meta is a mega tribe hated as they cant wipe everyone easily and have to hide on smaller area which they werent used to before extinction. And the mega tribes tend to be the loudest players online....
In a summary, Yes do some kind of anti titan artillery which will make megas go back to their favorite spots but PLEASE DO NOT BLOCK CAVES as they are the only things that make playing game possible for other then mega tribes and trolls....
