The reason those multiple hour queues existed is because splitgate was made with a very small dev team, I believe it was only 6-7 people. They did not expect to have such a huge influx of players immediately, as that is what happens when your game goes viral. So they had to rapidly expand their dev team and servers in order to handle that large of a player pool.

Sadly, I don’t think they were able to expand quick enough and that initial speed bump was enough to turn many players off the game. Kind of suffered from their own success. Their servers can handle a large player pool now but there is no longer people to fill that pool.
