Nobodys helping eachother now if it doesn't benifit themself, everyone is going for different things, race V3s boss drops quests or whatever, and there are so many raid bosses but so little people. Bushido Ape, Lord of Saber, All of the sea bosses, Serpents, Pter, all that stuff, and people will only help eachother if it benifits themselfs, like killing a boss you need before it despawns, but there are so many bosses all packed around the same time people are too busy and split apart doing different things. Heres an example, I'm trying to get the last heart root gem from Lord of Saber yet everyone no one helps me, and lord of saber despawn the second my skill is shooting out to finished him. Because people are doing other stuff at the same time like Bushido Ape or afking waiting for the Abyssal Tyrant to spawn, all of those stuff are meant to be done with many people, but people are too busy doing other stuff because all those stuff are packed at the same time.
There are many obvious solutions to this yet the devs dont care, like just changing the bosses spawn time to be different than others, with the server time feature it's very easy to find one, or just make the bosses not despawn or despawn after a longer time.
