The big earner really only helps if you're using the cloak and dagger, since you get cloak back by picking up weapons of the person you just killed with any other watch.
Also, trolldier is actually really bad, the best way to play it is without the mantreads and with the shotgun, that way you can still be viable while being an annoying jumping fucker.
The Big Earner is pretty much made for aggressive decloaking. Run in with no cloak, get a quick kill, back to almost full cloak from the backstab + weapon, cloak-disguise-repeat. The biggest downside is the reduced health of course. It's a hit and run knife with no staying power, and nobody really uses it because the Kunai is much better at it (go in, stab your way out, laugh when they can't kill you with your 180 hp overheal). It encourages prolonged cloak use, while the Kunai encourages aggressive play.
I never use the shotgun when I trolldier, wouldn't be sporting.
