From different feedback I’ve read on here and on Reddit, I think as long long as IMC doesn’t get better servers the only thing they could do to relieve servers and players is: restart servers twice a week.
1 restart at the weekly maintencance (tuesday ?)
1 restart before the week-end (Friday?)
Restart on tuesday wil releive the server from the week-end player rush.
Reboot on friday will releive the server from the week player rush.
It’s not the ideal solution but players did said that they lagged less after each reboot.
Please IMC, consider that simple solution for now because players frustation are going up and it’s sad because they like your game: https://www.reddit.com/r/treeofsavior/comments/4kdyoo/the_lag_is_unbearable/
