While playing in a team of 4 (even 3), the entire instance will stop, and start progressing 1 frame at a time. You can see a skill shoot off, here and there. We have found that it happens much more quickly when everyone splits up, and goes a different direction. If we stick together, it’s not as bad, but there are still spurts of latency.
Haven’t had this issue with 2 people, only 3 and 4
