Juggernaut is overpowered

I think juggernaut is overpowered because it gives u more health and thats really unrealistic cause no one can have more health then someone else. It should be more like body armor because armor using armor would protect you so you take less damage. Treyarch you should do something to even it out like it gives you extra health but the player cant run as fast or at all, less bullet damage, cant use it with second chance.




Anyone else agree with me on this?
