Forum:Orange rarity

I'm getting a bit impatiet. Some weapons are truly hard to get, right? But I'm not talking about Pearls, because I haven't even seen one. I'm talking about some orange ones, for example: Hyperion Butcher, Atlas Cyclops, Hyperion Bitch, Atlas Orge, Hyperion Reaper, Vladof Vengeance. I know that some of them are very rare, but all of them? Or am I unlucky fining tons of Volcanos, Equalizers and Defenders all the time?
