I also seen your having trouble with the arrow. I have an arrow as well and here are a few thoughts on builds and gameplay. Forget the machineguns. Just drop them because they will draw you into closerange encounters that the blackjack is not built for. Max engine and 3xLPL with JJs is what you run. Stay close in the second line behind the assualts and blast anyone with an alpha that pops up to shoot at them. Also you can jumpsnipe with it by hugging a ridgeline the enemy is close to then jumpjetting straight up and hit them with an alpha and then drop down behind cover before they can retalitate. We call it poptarting in this game lol.
