Well I just woke up and I read over the topic with numbers. The final results put the base numbers not counting levels close to each other with the exception of BL1 results included all DLC. The numbers after the leveling system show BL2 has more gun at every level.
Nintendo already pointed out what I noticed from reading over the topic. Most of that is irrelevant though, no one will ever see the 17 to 100 million guns by playing normally in either game. The same way no one will ever reach the bottom of the infinitely randomly generated dungeons in Torchlight.
What does matter is what you actually get your hands on. After all the time I've spent on Borderlands 1 on all 3 platforms I feel there is more variety in guns of Borderlands 2. I actually feel like I should fire generic guns WITHOUT red text because they may do something different than other guns like them.
Oh, you thought they made this game for you? You clearly bought the wrong game.
The point is that it is imo excessively rare. Like out of touch with reality it's only a video game excessively rare.
Eh. I think they could stand to be a tad bit more common, but I don't feel it's too bad. Oranges in this game aren't even on the same level as Pearlescents from the first game, rarity-wise.
Speaking of which, I think that might be why they made oranges so much less common in this game: they didn't want to have Pearls in BL2, so they made purples and oranges more rare to compensate. I think people are only so upset about it because most of them probably aren't used to playing RPGs with rare drops.
