I have zero issue with Rampage. I wish people would stop wanting to nerf nerf nerf everything they have a problem with. Adapt. It has a distinctive sound - you know when one is nearby.
I don't really care for it myself as I've lost too many close range 1 v 1s with it and other weapons are more versatile/viable (in my opinion) but if people want to rock the rampage and are good at it, let them. Adapt.
I always find it bizarre when people complain about stuff like this. "It's too common", "it's too OP"... .you're aware you can pick it up too if you feel that way right?
