When you say they one-hit light and medium body types do you mean with headshots?
And with that the sniper you used i'm guessing it was bolt action so how long between shots?
And after looking at footage of pax videos over and over again (the combat parts) it seems like the aim assist isn't as bad as halo I'd sad about the same as crysis 2. Then again it could be just the setting of what the people were using. And I think i remember reading an article where they actually patched some of the stuff after pax. Basically using it as a beta.
