I haven't read every page, but... could it be that people that prefer "the old way" are critizised because they don't acknowledge the actual need for adjustment? Ignorance is not always bliss. Try to understand that the software has a limit that forces Blizzard to take action, else every boss will be like Immerseus, Galakras, Garrosh, etc. No more "Just get the boss from 100% to 0%". That kind of makes boss design a shitton more complex and difficult for Blizzard.
Also, don't forget that some raiders quite like one or two patchwerk fights in a raid, even if it's only to relax between complex boss fights.
