Just customize it for open world, i.e. drop the spirit, take what’s comfy for you.
I’m running a high-DPS open-world build. Sword/warhorn/longbow, Signet of the Wild/Quickening Zephyr/Sic ‘Em (Signet of the Hunt is a good option to replace Sic ’Em with though). Marksmanship 321, Beastmastery 232, Skirmishing 111, zerker gear. I actually use a pet hawk and eagle, but it’s recommended that you use a Jungle Stalker.
