I’m on that server as well, but I haven’t experienced lag. Rarely, some weird things might happen. Like hit boxes not registering until enemies get close enough to melee strike. Or tonight, 3 of my musket shots registered the hit after ½ second from firing. These are very much the exception and not the rule however.
As nabbs mentioned, I’ve been tagging along ECRs every night and it’s crazy how many people show up with all kinds of things going on in battles. I haven’t experienced any problems. However, the open world zones were definitely not designed for 50+ people steamrolling them. Still, the server has been able to handle it from my experience.
For problems such as this, I would recommend getting technical and bringing forth evidence of the problem. Install CPU, GPU, disk, and network monitoring tools to evaluate what’s going on. That may or may not be in your realm to provide, but such evidence collection and analysis really does go a long way to help the devs troubleshoot the problem. Without that material, it’s guesswork unless the problem truly is widespread.
