You are disregarding peoples opinions based on their kills in difficulties that aren’t LFR in the other thread.
No ad hominem or what aboutism in here. Also no offtopic. A different tone causes people to react differently. Also the topic is also genuinely not similar, because as you yourself said, LFR is nothing like heroic.
If you’re genuinely interested in making this “EU vs NA”, try posting the very same thread with the very same wording in the US forums and see if people react as you expect.
I personally believe the opening statements were inherently too different and the “nerf LFR” statement was too fixated on blaming “pro hordie developers”, which is not only leaving a sour taste in anybody that you consider “pro” aka anybody who raids higher difficulties than LFR but also is just silly.
Sometimes LFR bosses are more difficult, sometimes less. If you had raided during Hellfire Citadel, you’d know what real pain in LFR meant. Archimonde rarely died with less than 20 stacks of determination.
6 wipes is not a large number for a bosskill.
NA and EU servers react very similar to similar topics, these two topics are simply not very similar.
Sylvanas might be a bit difficult for LFR, the one time I killed her we lost somewhere between 10 and 15 people during p2 only, but at the same time, free loot requiring a bit of time investment is genuinely not that big of a deal.
That’s about it.
