The amount of hammers that can be throw doesn't equal how many kills you can have. Same applies to golden gun. Also you are slow as hell. And have no extra mobility option (inonic blink, shade step, blink) The hammers have travel time and an arc. Basically meaning the effective "promised kill" distance on the hammer is not as large as golden guns. Lastly it has the same damage model as arc blade. You won't one shot many people mid super unless they were already wounded.
