In our efforts to improve account related services, we will be performing an exceptional global Blizzard authentication maintenance on 20/06/2018 from 02:00 until approximately 07:00. During this time, game logins and purchasing will be unavailable.
As of today we have a 35 man TS server (previously 25m).
Since we will most likely run 30m raids this gives little room for anything else. This means that on raiddays (monday, wednesday, thursday) you might get removed to give space to a raider. Yes on raid days, raiders have prio on TS :).
