I tried asking Crime City Mark this Question once but it was ignored. We all know that being a tycoon gets you more money (thats advertised when you go to checkout that goodfella upgrade.) I read in another thread that being a tycoon also jacks your def up a little to. (please correct me if I'm wrong) So knowing that a tycoon has an extra advantage over the enforcer and whatever that energy one is. I set out to find the enforcers "other" advantage. What I found was that after every stamina recharge, I also get another 4-5 free stamina. (I long as I use it in the fisrst 10 secs it's free.) Who knows it may work for the other classes too! give it a try and let me know if it works!
