If my headshot percentage is fairly bad (12%), would it be worth using the phantom more than the vandal considering I’m not fully taking advantage of the one shot capability of the vandal?

Now that Chamber receiving a lot of nerfs in the 5.12 patch, which sentinel is now best to unlock that can be use in offense and defensive roads? Killjoy is now better?

Or at the very least give you half the RR your supposed to get, I was playing a ranked game went 38 and 14 but the enemy team wanted to draw so I got zero RR for playing the game of my life I was so angry
