People overrate the word difficult. They think fights that take a long time all belong in that category. Some fights just require a gear check. Hard is Yogg 0 where even people with gear couldn't get it down. It had many different ridiculous abilities. Skill level has increased too.

Garrosh cannot be compared to Raggnaros OR Lich King, because Garrosh simply isn't that mechanically complicated of a boss. You skip an entire intermission on heroic, and Enrage isn't even remotely close to an issue (kills range in the 15 minute timeframe, with a boss enrage of 18 minutes).
You let me know how a boss that took roughly half the attempts of Heroic Ragnaros, Heroic Lich King, or Heroic Lei Shen is a "harder" boss than those before it.
Pacteh likes to talk a lot of smack, so of course the one time they get a final boss overall first (without Paragon beating them to it) he is going to act like it's the hardest thing ever and they did nothing short of a miracle to kill it. Read the ManaFlask article, Pacteh talks about how amazing Garrosh was and how it's the number 1 fight of all time, and the other guildies didn't rank it anywhere near as high as he did.
It's also worth noting that they wiped for HOURS on Blackfuse the night before and same day as their repeat Heroic Garrosh kill. They 2 shot Heroic Garrosh, not counting the ninja pull insta-wipe they did shortly after the Thrall RP. It would have been a one shot had the rogue they had kiting an Iron Star not been picked for Malice. Blackfuse is a mechanically harder boss than Garrosh. Paragons is more of a gear check and a "figure out the right kill order" boss, and Garrosh was a gear check. An end boss deserves to be more than just a "have enough gear to skip an entire portion of the fight", and a heroic-only phase should have more than 2 easily controllable mechanics.
More pulls went into Blackfuse and Paragons than Garrosh. Think about that.
Everybody notes that player skill has increased yet I do not believe that at all. I believe that playing your class with more efficiency has simply become easier, I know for a fact that I haven't drastically changed my playing style since BC, which leads me to believe that most people that have played since vanilla haven;t changed their playing styles tremendously either. This leads into my thinking of skill remaining the same, the raids have become easier simply because each class has so many tools now. The mechanics are more complex to make up for the abilities given to each class with each expansion. The difficulty is not increasing, vanilla was simply harder because gear hurdle was there to float bad players, without the gear you didn't have enough decent players to complete a encounter. You also had to coordinate many more people, which wasn't easy at all (early days seem comparable to a bad LFR).
One thing to take into account with those numbers are repeat M'uru kills. For example, the only other guild on our server that killed M'uru didn't kill KJ -- they had problems with repeat kills in the subsequent weeks after the first kill, killing him only two further times. People quit and that guild stopped progression until the massive nerfs in 3.0. In a month they probably only spent three or four nights on KJ in total.
That was why he was such a guild killer -- aside from being ultra-tightly tuned the fight was incredibly monotonous, so people burned out on him.
No Garrosh isn't the hardest at all. I have friends in higher up guilds and they are currently on him or have killed him and say that Blackfuse and Klaxxi are much more difficult than Garrosh. They almost compare Garrosh to Ra-den and blackfuse to Lei-shen.
And KJ was miles easier than Muru... My guild took 203 wipes on Muru and around 50 on KJ. Since you seem to want credentials, I am/was Brunnor/Sendaii of Crimson on Greymane - Main tank at the time as well as Guild leader and raid leader.
I found Normal garrsh as challenging as normal Ragnaros. Sunwell was insanely hard... Maybe too hard. I'd like it at the end of ever xpac we got a mega hard raid with one boss kinda like Halion where it's just one boss and a tease for the new xpac.
