It's easier to assume that all missions have a bonus objective of "kill 30 dudes"
I certainly prefer it to the old system of running back and forth to kill the guys, then having to get back to the quest giver only to be told to get back there and kill the slightly larger guy.
GET THE HELL OUT OF MY WAY!!!
No, I don't want to talk to you, I want to click on the friggin objective before- ...Oh look, that other guy got it. THANKS A LOT KHEM.
Every attack that is launched at you has a chance to be deflected. It's automatically calculated based on your stats and level. There's no way to control it manually.
Let's not forget "You have my COMPLETE undivided attention."
It's kind of a shame, but considering the sheer volume of voicework in this game, I'm not surprised that this happened.
