We do get 5 times the drop... when it actually drops though! Weren't the drop rates supposed to be buffed too? It doesn't help people who don't drop them at all.
If you have spent hours looking for a certain resource and not got at least one of that item chances are your doing something wrong, I have managed to get every type of "very rare" material I need in relative short order if you use the forums here and 3rd party websites. I know sometimes its hard to get what you need even if you know exactly were to look but I have managed to get pretty large amounts of all the rares in 1 to 2 hours each while looking for that specific item ie. if I'm looking for Polonium I tend to find about 4-10 and hour, this has been the case for everything I have actually gone looking for. I did my research and found out the best places/activities to do and had posititive results on all of them so I can only assume that its really not that hard to get the stuff you need if you do your homework, either that or I have been extremely lucky. The one thing ED is very poor at though is giving details on how to exactly obtain said items, a good game design means players seldom have to look outside the game for answers to these sort of questions
