I think some people are going to scramble for reasons when their favorite guild loses, so here's a list of ad-hoc explanations that you can use just in case:
"It was just about raid comp, not tactics"
"They had a huge advantage, raiding in their native language"
"They exploited the fight by stacking Rogues/Boomkins/Hunters/Whatever"
"Blizzard favored the other guild, a reliable source told me"
"They raided fewer hours so they are more skilled"
"Their main tank got DDoS'ed for 24 hours" (ok only if that's Nihilum)
If all of that failed:
"<insert guild name> is still the best"
"I have my own progress list in my alternate universe and my favorite guild got WF on that one"
And in other news, REM killed Xhul'orac, world 4th.
REM 10/13 with Xhul down !
Why do people say Mannorth is one of the hardest bosses? I haven't done him on Mythic, but his mechanics seem really simple, at least from normal and heroic..
Nihilum 8/13
In terms of difficulty it does not seem that much harder over all. One or two new abilities to deal with but that's about it. However on normal and hc mannorths tuning makes him probably the easiest of the end wing boss. In mythic it's assumed he is tuned to a point where he is the hardest of them. That means while it isn't that hard of a fight , you need to be it near perfectly to get a kill and with the gear pargon and method have (way way worse then you're meant to have when doing that boss) it also involves no small bit of luck on trinket procs etc coming at the right time. If your trinket procs when you are say soaking something and won't be able to damage for 4-5 seconds then that's a massive dps increase down the drain
