So, as wished for, -1. Too many folks with the perks to up over and over with the big one.
But, it would be interesting and something fresh. I would want it added in a way that promotes combat and action. Climbing to 30K, hanging out and waiting to see if that dar bar is a single 29 with the bomb is fine but the ratio of loitering time vs fighting time isn't my favorite.
It would need to come with some mechanism that encourages a fight. Basically, it needs to have the opposite effect of what the real ones had.
