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.
