Every class has at least 1 traitline designed for healing and support, e.g. Some classes like Firebrand or Weaver can even give up on Expertise and boost burning to 100% with runes, sigils and traits.Дў. Condi is easier to optimize, because you can run it only with Condition damage/Expertise stats. Many decent power builds can comfortably handle the Security Golem HP in Verdant Brink, as long as you are hitting your dodges.Д«ut a power based class in something like Marauder's may start to struggle under the heavier burst damage of a Desert Bounty, where a Condi Build like Shortbow Soulbeast in Trailblazers will be able to take a few hits and passively resustain itself via posion application and Predator's Cunning.ДЄ fair bit of soloing truly hard Open World Champions is L2P, but having a build and gear that allows you to make mistakes like blowing a dodge or mashing the occasional power off cooldown is huge quality of life and there are just more Condi options for this than there are Power.ДЎ. Most of even the glassiest power builds can handle the Giant without problem as long as you are mitigating the grubs, not camping in red circles and dodging the stomp. There is a big difference between the Risen Giant in Cursed Shore, the average HoT Hero Point and a Desert Bounty.

That said let's be clear about what you mean by 'Champions' in Open World. This level of sustain in addition to solid damage is what makes these builds a better tool for the job. But a condi Scourge or condi Shortbow Renegade can techincally leverage all three at once. Some power builds can approach near the level of benefit from a source or two like Power Scrapper from Impact Savant, Power Reaper with Shroud or Power Spellbreaker via Might Makes Right. Condi based builds that deal in the Torment condition can gain another source of sustain from these runes. There aren't many viable power based solutions that approach these trait's effectiveness.ДЈ. Traits like these offer healing based on condi damage done or vuln applied. Secondary Sustain from traits like Parasitic Contagion, Predator's Cunning or Dance of Death. Condi damage builds lose much less in their damage output from running this or Dire Gear than a power build will for offering comparable toughness and vit via something like Soldier's.Дў.

The short answer is 'yes' condi builds are generally better for this.ДЎ. Are condition based builds generally better for this task then power ones?
