So, what's the deal with those rare weapons?
First of all, they're not really that "rare". I've received all of them several times by now, they also appear in the shop now and then, and I usually keep them because they look funny, not because I actually use them.
Which leads to the second point: Are they supposed to be more useful than the "normal" weapons? Because that's what I expect from a weapon that is rare or hard to obtain, but I don't think it's the case. The Drake spreads the pellets even more than other shotguns, the High Roller is slower than other machine guns, the Pale Rider magnum is indeed powerful, but also slow and has a very small ammo clip, and I don't really remember what the Muramasa rifle was like, but if it's so forgettable, I suppose it wasn't that great either.
What do you think about rare weapons? Is there anything special to them that I'm just overlooking?
