Devs and maintainers probably live in a checklist and delivery countdown.
Why not helping them with the several netcode devs that sometimes test mmos in their spare time?
The game has performance logs, devs could shortlist interesed users, expose problems and diagnostics in a secured dev console (or better outside git, subversion, etc because remote executions), call for code fixes and pay in irl cash. Or offer tokens as part payment. Who knows if the lag problem is because they lack certain custom library.
