Oh man I remember Planetside 2 launch being so insanely laggy and buggy lol
At some point we threw grenades on a giant pile because they just never went off, or sometimes just disappeared as soon as we threw them. I don’t think the devs ever tested that huge influx of players anywhere in the pre-launch stage. It’s hard to predict some things that will go different from testing to live, but man it seems so obvious with large multiplayer titles.
Even WoW still struggled with this, servers becoming laggy and unresponsive even, it’s been better last 2 expansion launches but it’s still not great. And they had over 15 years of data to go on too.
