If Blizzard thinks they can kill off that which enables bots/macros/addons to do <things> too fast for their liking by making the looting process take longer on world objects without making too many people ragequit, wouldn't you think they'd do it? With WoW in decline, it's unsurprising they are attempting to staunch the bleeding by claiming to support the wishes of The Average Player. (Note I said "claiming," which I think is an important specifier.)
