Hello :- )

1) Since i prefer heroic DV over heroic DBW I would say the same for the normal version comparison. As hunters mostly struggle vs high armor targets (Hpal, Warriors, Ele shams with shield) you want to keep ARP as low as possible. If you wonder why check out my arp hunter guide for pvp http://forum.warmane.com/showthread.php?t=409807

2) Not too much as trinkets don't play a major role in hunter gameplay. We ain't relying on trinket procs like casters or melee dps. We don't do a go on the basis of procs.
