That's the thing, people can be selfish because... they can.
It is open world, there are no rules, and the rules made up by the community cannot be enforced
If you are spawning a Tarchia in Ahm Araeng and you didn't set your res to the nearest Aetheryte and somehow someone doesn't res you (very rare) you are screwed.
If you spawn a Bird of Paradise, very squishy HW S Rank that can get nuked easily, and that Squonk is on the other side of the huge Sea of Cloud map? well tough luck
If you are a spawner and use no third party tools, and you are not narrowing down the S rank spot by killing B ranks in the area to give yourself a chance to know where its gonna spawn and get there in time, you are decreasing your chances to get it, this is what Jojoya means by poorly prepared
The only randomness is when the S rank will be available in that window, the where can be figured out
It would be amazing if people waited but hunting is the Far West, it's much better to be prepared for worst case scenarios, and if you miss some, get the next ones
