I would argue that they are not made to combat any particular kind of enemy, rather they are shown combating particular enemies. Just because we don't see Ruby fighting Giant Armor doesn't mean she couldn't and vice verca, also according to the Rules of Named Weapons in Anime neither weapon may break the other unless an antagonist is involved and the writer wishes to send them on a reperation quest. I also don't buy that Ruby would have any troubly useiing Crescent Rose as a sniper rifle, mostly becaus Monty wouldn't give a character a weapon function she couldn't use, but also because only the tip is in the ground, she can easily ajust her shot, the only trouble she might have is shooting down, also there is only a one second delay between her fireing a shot when she's snipeing and her fireing again after reload. As for the binding thing, it takes about three seconds to cast and we have no Idea how fast Ruby is going, or If the binding spell is directional, depends on line of sight, or if it has a range. The red spell would actually help Ruby, she would just spin Crescent Rose the opposite direction attacking with the short bade on the foot of it before bringing the main blade to bear again. As far as why they fight I think holodeck or mind control make the most sense, and where...hard to say, there is no terrain that comes readily to mind that doesn't give one a disadvantage...

Also to the wikia contributer directly above me, I completely agree, but this is still fun :)
