I think quite a few people liked going back and doing (moderate amounts of) old content for a current reward. Did the people who had already done those zones repeatedly on farm enjoy it? Probably not. Does that constitute your "most of the raiding community"? I doubt it very much but I don't think there is any way to accurately determine it. My guess is that the average raider in any tier didn't see the previous tier, let alone the entire expansion.
As to trying to pug pre-nerf hc content, yes it can be done and should be possible. I want the community to get rid of this bloody stigma that is attached to pugging away. It is as bad as the hardcore/casual / 10/25 / etc of hogwash. Every bit of content is capable of being done with a pug, a pug does not, by any means, relate to any difference of work required. In earlier times it was quite common to have a good amount of pug's in your group due to various things; the drop to 25/10 lessened this. Not that didn't throw it out the window though, it just placed more responsibility on the people there.
In tbc we typically pugged 2 alt runs every week for bt/mh (pre-swp) most people on most servers rarely even saw this content but yet it was pugged. Swp didn't see much pugs until 3.0 but those of us in there before that patch can understand that. Muru was a guild killer, brut had high dps requirements, rest needed a large amount of coordination. Past that patch it was fairly common to see pugs for this, yes they had to work hard but it was no less than guilds. Hell some guilds still never even seen this content.
Wrath rolls around, and this became even more pug friendly, raiding is starting to catch up. Players are getting better, things become easier, not that the content was extremely hard either... My giant blueberry tanked our server first S+3 kill, so things are not brick wall or cake walk. There are still guilds that struggled with progression, and there was pugs that could breeze through the content at the same time. My weekly pugs got many a HM uld/togc/icc/fl/ds kills before tons of guilds did. Why? Because we worked, people did their job, and those that lacked was gone. Sure bad pugs can happen, but again that comes with the territory same as guild runs. It all comes down to the right leader, communication, proper selection, and effort; again just the same as any guild.
Remember us as the raiding community is still only a fraction of the player base. <5% cleared original naxx, <5% cleared swp pre3.0 and not even 10% has cleared hm ds still. But just because all of the people are not rocking the same guild tag, doesn't mean they cannot execute a scripted encounter as good as those who wear a matching guild tag.
There was no "farming" needed as you said, and well aware of the farming that happens. We have farmed 5 different staffs for recruits past 4.3, many of the uld mace, hell even in tbc we farmed illidan for 80+ kills and never seen a mh glaive drop at all. I had an off hand and our fury had the other off hand that dropped but never a single mh, same with classic content as well, the staff, tf, and sulf.
I am extremely aware of farming old content, but that has nothing to do with the topic that this was on. That is a problem with legendaries. Yes I firmly believe that all the legendary models that have been in game have been bad and that they should be no more, but this isn't the debate for that atm.
This has to do with the weekly quests. In which I believe, and stand by the idea that they could come back but will only work properly if they are for non-relevant content. Do I believe they should give a currency, no because the currency system has changed a whole lot since back in wrath. That model wont work well, in my eyes, but other worthwhile rewards sure. It would be kinda hard to make the rewards not mandatory though which is why I think currency shouldn't be the answer. Which most of us raiders get capped from just the raid alone so if it gave vp, why should I do it?. Maybe consumables could be nice, since you wouldn't "need" to get them but helpful to do so.
Apologies, the reference to Legendaries was in no way a directed rant at them, merely an example supporting my statement that most people resent farming out of date content. I wasn't saying that "Kill X Boss" quests were inherently bad, just that I highly doubt Blizzard would choose too use a model of it that put players back into old content again. Which is what my previous post was entirely about, not how legendaries suck.
If this is a another way to get Valor Points, where there are so many ways to cap, it could work.
I was referring to Guild Wars 2. There's a lot of reasons why that's kind of an odd comparison to make though. The biggest are the lack of monthly fee, and the fact that the first Guild Wars wasn't really a "true" MMO in the traditional sense.
And, of course, the game hasn't released yet, so it's still feasible that it could flop.
I run in a 25m and 2 10m guilds now and very few people in those saw enough of tier11 to have said they farmed it. Most of them either barely saw firelands or have never stepped foot in it. Its a constantly changing cast of characters and maybe when people return from D3 en masse there will be less turnover but for now I see very few people with a consistent raiding background which I think is pretty typical of the last release in an expansion.
