Well, how about HP? Some months ago I got into an argument with someone on these forums about this very topic and I went to the effort of recording the HP of all the Goblins in the EA and averaging their HP. That includes the HP of boss Goblins, which have HP >20. So, including Goblins which were specifically designed to be bosses, the average HP for Goblins turned out to be 11.75. 11.75, happens to be a value within the 2d6 range. There are many Goblins with 3-4 HP, there are also a couple with 15 HP or higher values. 2d6 happens to be a range, not a fixed value, so even if you look at just the smaller pleb tier goblins, you can expect some to be at the lower end of that range and others to be at the higher end, with some deviation.
That's not how numbers work. You can't just have a range and have the average basically be the maximum and call it good. 2d6 is already a range between 2 and 12 with an average of 7. If the range is 3-15 with an average of 12 then they've buffed HP that's literally how maths works.
