I normally cba to change my streaks once it's available and I prestige soon after anyway. Not going to spend a permanent token on it. Got a few in care packages though. Plus everyone always seems to switch to blind eye or hides inside when I see people use it, they hardly get any kills. Highest I run is dogs. Gonna spend my next perma unlock on dogs so I can get some use out of them without waiting so long.
Quit running it after it hit a thousand kills because it is the single-most surefire way to ruin a perfectly fine lobby. The chances of everyone on the other team leaving are so close to 100% that it simply does not measure up to that one 100+ you might get in the legendary coincidence that no one leaves.
Dogs and Lodestar are in the same boat, pretty much. Third row of scorestreaks masterrace.
