I like the idea behind the new Arbites background bonus (and making the old one into a Talent is neat idea), but I think to be consistant with other similar abilities it should either just give a reroll or require a fate point be spent to gain the DoS equal to WPB, giving both and not requiring a fate point seems overpowered.
Dive for Cover is a neat special rule and a good expansion of the Dodge skill.
Unless I'm reading things wrong, the change to Blood Loss is huge. Blood Loss is no longer potentially fatal?! Instead, it just makes you tired. Don't get me wrong - I like it a lot but it's a big change.
