My opinion (no VR14, only some VR4 to VR8 chars):
I get several blue items from different mobs inside a quest area in let's say half an hour. I did not count them but there are different ones and I guess about >5.
I don't feel to get these items not often enough, though sometimes it could be more, you are right.
What I experienced is the fact that items with a purple color will only drop very rare, and if they drop you won't get another purple one in the next minutes. But I did not count the minutes.
This is ok for me as purple items are rare and that is why not every 3rd mob will have one (it was actually only frustrating that a spider dropped a purple healing staff..I was thinking about "Hey, that is how they run to the other dead spiders and feed on them. They don#t feed, they use the healing staff! Bastards
)
So you might be right but, for me, I don't really care about it
