Praetorium CS skipping by closing out client.

[Shibi]

The tank will close their client and relog in and start the final fight ahead of everyone else. I've seen DPS do this as well.

Most people who serial run Prae have learnt from others that the French or Japanese Audio makes the exit from cutscenes quite a bit faster.

Disconnecting and reconnecting leaves a chat message. Next time you see people fighting when you exit the wordy, verbose, long, and lengthy English audio and others are already fighting, you can check if there are telltales of this in chatlog.
