Blessed orbs not "correctly" randomizing.

After a decent number of tries it became pretty obvious that blessed orbs are giving numbers in the mid range instead of being truely random. Lets say the number should be between 1 and 20. Probably above 75% of the time the number I got was between 5-12. Now maybe this is how it's intended but if so that's pretty dumb. I realize other things in the game aren't a true random either (like gem sockets and links) and I know there's "sort" of a good reason for that. But maybe this needs to be changed. I know there's a point to not make it easy for every single person to get the best stats on any item but practically never isn't really that awesome either. Anyway, maybe this isn't really a bug and is working as intended, if so this maybe isn't the place for this, but I thought it was worth noting.

This is almost certainly intentional. And personally I do not think it is dumb, it is exactly how I would do it.
