Hello,
For around three weeks since the new update, Australian servers have been have ongoing, intermittent issues where ping will spike 150-250 or so ping for the entire lobby. Sometimes server latency will return to a normal range in the match or after a few matches, but the problem has been ongoing. This has been making the game uncomfortable to play for everyone involved, and I have personally been avoiding ranked because I cannot trust that the servers will remain relatively consistent when playing.
