There is no way they were 1 minute over the enrage. I remember Patchwerk from vanilla. Once he enters his time based enrage, he literally eats your entire tank roster in a matter of seconds, and then starts going down the threat table from there. If he had been one minute over his enrage, the last 55 seconds of that video would have been watching the raid scatter based on threat, trying their best to play pingpong with patchwerk as he chased them down and murdered them.
In that video, you see the following:
Ingame Time stamp 4:43:06: Draup (running the boss mod) annoucnes Patchwerk Engaged
Ingame Time stamp 4:50:54: "Patchwerk enrages". This would would be the "fixed" enrage he does when he hits 5% health
Ingame Time stamp 4:51:05: "Patchwerk Goes into a Berzerker Rage", which is his Time based "you done took too long and Im going to murder the hell out of you all, enrage. At this point, you see all 3 remaining tanks drop nearly instantly, Patchwerk goes for the person recording the video who iceblocks, then Patchwerk dies like a second later.
That's no where near 1 minute over the enrage. That's a pretty nearly perfectly executed first kill.
It does make for a bit of headscratching tho, as the mod clearly calls out a 7 minute enrage mark (6:38 timestamp on the video), but the fight appears to have lasted exactly 8 minutes.
Spotted it: Something wierd with the boss mod reporting at the 6:05 minute mark on the video the Recorder has a boss mod only channel open, and you can clearly see it calling out 30 second intervals. However, patchwerk kills a tank at the 4:49 ingame timestamp mark, and the bossmod appears to skip an entire 1:30 seconds?
4:48:06, Boss mod calls 5 minutes
4:48:36, Boss mod calls 5.5 minutes (still accurate from the Boss Pull timestamp)
4:50:06, Boss mod calls 6 minutes.
entirely skipped the calls for 4:49:06, and 4:49:36. Not sure what is going on there.
