It is. A well placed wall during a hack can block enemies from entering and keep everyone safe. You'll get enough points to max out two passives and two combat skills with one point in your least favorite skill. But that requires the rng gods to bless you with up to X cards for your particular character. What weapons are you using? Stick to the lowest tiered packages if you're only playing Bronze, the resupply and the next one above (Basic I think?) to max out your weapon drops and mods. If you get the Charger pistol, it's quite a competent gun maxed out even on Silver matches. Balance changes should be happening any time soon because combos seem a bit underpowered right now.
