Okay first play through I ticked off Ceasar, and got his hit squad on me at level 12.
Almost did not survive that, but I was vilified with the Legion so I understand why they sent it.

Now I am playing my Legion run through I am level 6, and just got told I have 3 days to make it right with the NCR or I get hit by the rangers...
Okay I would understand this if I was vilified, but I am only shunned... hell I just walked into one of there camps, and they don't even attack me yet?
Are they really that... insecure?

Okay so I have killed a lot of them, but all but two attacks where unwitnessed.
Just two hits...

I had killed the four legion in Nipon, and there entire base at the Cove before the Legion sent a hit squad at me.
Does the Ranger thing go off the number of NCR you kill, NCR high targets killed, or rep?

I have killed both named NCR members at Primm, and I had the Ranger chick show up after I had just killed Ghost, but I had done it in stealth, and no one... NO ONE seen me do it.

I hope the two hours it took me to wait for each NCR member to go down the stair case at the NCRCF alone so I could stealth kill them was not in vain...
I want to go way anti-NCR, but I am going more ninja... or at least don't want to play my full hand this early in the game.

Its like in The Ring, you have a certain amount of time then you are brutally killed...unfortunately you don't even get seven days in NV. At least in NV you actually get a chance to prevent it.

Whats funny is I always killed the hit sqaud that shows up to tell me in three days I'm dead. (might as well save some time xD)
1 day later the same people who I just killed showed up saying in two days I'll be dead so I killed the ghosts of the people I killed the day before.
Next day the ghosts of the ghosts I just killed the day before show again (wtf really?) "you have 1 day to live" so I killed them again.
"Since it has been three days and you haven't improved your rep with NCR were going to have to kill you." Now what did the last 3 lessons teach you? Apperently nothing.

On my next playthrough I had legionary hit sqauds and NCR hit squads rolling in the same posse to kill me. (Enter movie trailer) In a world where two mortal enemies join forces to take down the greater evil leaves a lone wanderer fighting for his life coming to all theaters soon.
