Not sure why problem is in quotes, it’s definitely a problem. It’s also not unique to LE at all, there are just better solutions available in other situations because of related factors. The other option we had available was to put a zone transition party popup window, similar to what you see in D3 when entering a boss room. This would let everyone transition at the same time and it would allow for additive loading. It is also what happens in the monolith already. This is acceptable because everyone is in the rest zone so we can kinda put everyone in a bottle and change the echo that is loaded on the same server. We have looked at some other solutions that have been implemented in other games. Well, as much as we can given limited access availability. I am very aware of POE’s transitions.
