Using long standing game mechanics the way they're designed is not an exploit. SE made tank LB3 do what it does, and SE made LB not go up as quickly with duplicate jobs, deliberately to encourage people to not bring duplicate jobs.

Players reacting to that by not bringing duplicate jobs is working exactly as intended.
