1) It's got the shortest range in the game, ergo it gets the highest damage output. If it didn't have such a high damage output nobody would choose it and they'd simply stick to quick-melee for CQC.

2)The Extendable Drillbit upgrade also increases the quick-melee range for the Drill, which is why the rate-of fire decrease applies to it too. I see what you mean, but don't worry, it'll still deal more damage than any other weapon's quick-melee attack.

3)The Deflector Dynamo upgrade gives you a personal shield, offering full frontal protection. It's like the Riot Shield in MW2 but even better.
