Well I use to hold back and set traps with the trip mine but now the trip mine is nerfed it's does not kill them so I have to pick up after it and it's not a trap anymore cuase they can see where I am on radar. Night stalker I find the bombs useless but will try vortex from now on. Blade dancer is okay but I don't like it's need to be cqc so much that you just end up getting shotguned.
