Just had a quick game of dust, it's definitely a lot better. Hit detection and registering is a lot better. Health wise it's now a little more than MAG. If they keep making the improvements they've been doing then there is no reason why this won't turn out to be the biggest sack of shti going. Speed wise though, it still feels sluggish. But maybe the devs are going for that sort of heavy shooter feel. My only hope is that vehicles are easy to destroy. Because someone just went 23-0 and all he was doing was spawn camping in some sort of tank.
If you've ever played killzone 3 online it reminds me of something like that. I think its going for the heavy feel which I most relate to in the Killzone series, sadly whilst i'm fine with it for campaigns I HATE! It for online.
