Alright, here we go.

What feature from the original APB did you like and do you think should remain in the game, explain why!
Drive-by shooting. It made for amazing car chases, especially when you were in a car with 4 people and that one song comes on. Those moments made the game what it was.

What feature do you believe needed a complete overhaul, again, explain why!
Plenty of things, but mostly the upgrades. Everyone used the same 3 weapon upgrades: Rate of Fire, Damage and Accuracy. And for character upgrades, increased health. There were a bunch of other upgrades that were simply outclassed. Coupled with the unbalanced weapons it made the game extremely unfun, especially when you're a low rank rookie getting killed by stat-padding pro players.
