I wouldn't say Signal is the only one that does it. I mean Pyrrha comes from another region and her weapon seems to have the same transformative style as Ruby's and Yang's weapons. Besides Jaune, most other students have some kind of complicated weaponry, as even if Lie's weapons are fairly simple, he can apparently just slip them right into his shirt without the blades cutting it every time; so there is more then just the guns, but some kind of storage device in his sleeves.

As far as the stronger and smarter thing I keep mentioning, that is most likely contributed to Anime-logic. I mean no normal human could accurately measure how the recoil from a gun-scythe would send you flying in a way you could use in combat like Ruby (not to mention that landing move she does when she spins around the tree with her scythe would rip a normal person's arms off). Yang is able to shoot Junior's rockets out of the air when they are all moving relatively fast. Lie is able to spin down a tree when in reality that has no shot of really happening; and Jaune was launched high into the air by a scorpion Grimm and will most likely be just fine. Some of these examples could be the result of Aura, but so far the only character we have seen to use any advanced Aura abilities is Lie and maybe Yang (Pyrrha only unlocked someone else's aura so that doesn't count).
