Yes indeed, people were totally satisfied in 2015 (sarcasm)...

And as many, many, many, many, many, many, many people stated before. The breakpoint, from which it is too late to come back and generate population was reached already a while ago, I myself and many others said that.
People won't forget, that critical updates, which were high voted in bugtracker got ignored for so long.
Examples:
-) Disengage + grip crashing all people around in BGs, arenas, world. (bug, that existed for years)
-) Fire mages mastery disabled to "fix" which made fire mages useless in PvE completly
-) Dash from druids bugged (they could just shapeshift out of roots during the full duration of Dash)
-) You still can't complete BWD (Nefarion not scripted)
-) Throne of the 4 Winds was and maybe is still completely bugged
All those bugs are gamebreaking for either PvP and PvE, were upvoted in the bugtracker and not touched for a long time.
May I remind you, that rated BGs would have never been enabled if we didn't open a thread where we
literally had to beg the staff to open it.
And rated BGs still don't work properly, they basically are the same as normal BGs now, just that you get rating and achievements. You can use potions, flasks, nitro boots, bufffood and you still can't fight your own faction.

Oh yea I nearly forgot, may I remind you about the staff barely ever interacting with the community on forums. The only posts from staff members I see are when they close drama threads, but I haven't seen any staffmember helping out or answering questions in the Nelth forums for quite some time.
And yes, you are right.
They do fix some bugs, but as I mentioned above. The breakpoint was reached some time ago.
Changelogs are important for the community also. That way they can easily check what got updated, finish those achievements, raids, whatever it is. I still don't understand why they don't just put a changelog for cata if they fix so much.
