You can also tell based on the number of blocks from release day up to now. I played pso2 since release and like ive said, on ship2 almost 5blocks are always overpopulated and with block numbers reaching 130+ i believe. and now look at the state, blocks less than 60 and only 1 is overpopulated.
138 blocks was reduced back to 119, 100 (iirc) and 80 a long time ago. Before my 19 July screenshot earlier. They were only increased that much to begin with to deal with the PC launch spike and had never been needed beforehand (prior to a few hours after PC launch there were only 60 blocks and their use was similar to what we see now). The reductions' main purpose has been to reduce the need to scroll to change blocks to join others or use the ship-specific challenge mode blocks. You shouldn't be using the number of empty blocks to conclude player counts anyway, but as I've noted a couple times now taking numbers from the period covered by the PC launch spike to say the game has been dying since that spike ended is not wise.
At this point, either merge some of the servers or give the small number of people who are still grinding the ability to play without having to wait for a long time just to fill the group up.
What would this solve? nobody is running the triggers you want to do on any ship. You just want to combine more people who won't run the triggers you want to do. Despite this repeatedly having been explained throughout the topic you're still looking for the wrong solution to a problem. It's the quest itself being slow and unrewarding that's the problem here.
