Tri-bolt with scavenger was working at first for direct-hit kills and now the bolts just blow up. I've literally tried everything and It's nearly impossible. Mess up twice and you're screwed. You can't knife for more ammo, because that messes up the aspect of using ONLY the crossbow. Boosting will get you banned so that is out of the picture. They're asking for 83% Accuracy without dying using a crossbow. Ridiculous. And you can't replenish ammo if the tri-bolt screws up twice and blows up. Hardcore people just run around with shotguns and SMG's spraying like hell. And people use their cheap ass moves with flashes, kills from behind, camping, Assault shield + Combat Axe, Random Shock Charges, Hunter killers that ONLY go after me, and Spraying with LMG's I'm sick of it. Hardcore, Sticks and Stones, Tri-bolt + Shock Charge, Tons of perks, I've tried it all. Nothing works. All the bull I had to go through with the Assault shield, Ballistic knife, and Combat knife, only to be stopped by this one challenge for the crossbow. I don't even care if Treyarch doesn't look into this, There needs to be word around that too much is asked to get diamond camo. Innovating Ideas, but this just doesn't work. Mw3's system worked, you had to get a million kills and finally get to level 31 only to prestiege and lose it. Made you work for it. All blackops is doing is just frustrating the user. Not only that, but People are going around with prestiege master with only 25 kills on their card. Everything diamond and all. Not a thing done about it. So they take the easy way and nothing is done while I work my ass off going through bull and I don't get it but they do?
Plus, The blast radius for the crossbow is too low. I understand the issue of being overpowered but grenade launchers do a better job of being over-powered than a crossbow does. despite the fact that they've been nerfed several times. first off, the only problem with the grenade launcher is that it has a parabolic trajectory, easy to deal with the sights since you just aim a bit higher and the sights help you get an Idea of where to shoot. Then you also have the velocity of the gun is not as fast as a bullet so your shots might not be in real-time with the enemy's movements. So the player is left predicting where the enemy's next movement will be. Pretty easy to deal with since the blast radius let's you be off just a little and you'll get the kill.
The crossbow on the other hand is treated like a gun, the hipfire sights are like a normal gun and It's all about accuracy. The same problems as a grenade launcher but the blast radius makes it so that you MUST get a stick to get a kill. Not only that but you must wait for the timer to finish to blow up the bolt before someone else steals your kill. You are still left predicting where the enemy is and the trajectory may off-set long-range kills, but the blast-radius and the detonation time makes it so ridiculous that you have to deal with that and the fact that others can steal your kill and that you have to always hit them dead-on or you won't get the kill unless you're lucky. All of that with only 6 bolts, and 5 kills without dying.
