With an 11% wheelman, and 11% mastermind,
Settle a Beef: Permananatly has the best ratio with 35 Energy for 71 XP.
(2.03)
Bank Heist is second with a 8:16 ratio, or (2.00).

However, with an 11% wheelman, 11% mastermind, AND a private island (5% additional xp recieved from jobs, Underboss mastery reward), it’s a bit different.
Bank Heist becomes 8:17 (2.125) and becomes –> the best, most energy efficient job in the game <–.
Settle a Beef becomes 35:74, or roughly (2.1143), which is EXTREMELY close, but is second to Bank Hiest. However, they are so similar at this point that it would be better to just do Settle a Beef to save time.

Scott, drop rates can be pretty low. Even if the drop rate for the AR-15 is 2 percent, the _expected_ event would only be at 50 times. You could just be unlucky. Keep trying. AFAIK, you are doing everything right.

i think above qty are for default considering you didnt promote any top mafia of yours and on contradiction ,well varies on how many % attributes you top mafia has… qty needed decreases at the % of attributes increases

PS . got this on one of the facebook mafia thread

Would be usefull to know that say at the “Hitman” level that the “Frame a Rival Capo” job needs to be done 20 times which means that you need the 40 wiretaps. These numbers are just examples.

9 – Boss Settle a Beef… Permanently 68 37 183.78%
2 – Associate Bank Heist 16 9 177.78%
9 – Boss Travel to the Old Country 86 49 175.51%
4 – Enforcer Run Illegal Poker Game (+prep) 63 36 175.00%

Interestingly, Bank Heist is almost the best job.
