Revenge of the Fallen creates a moral hazard problem. You never want to be downed, so why make it better for you to be downed and create that mindset that it's less bad? In essence, it's a wasted trait that isn't utilized most of the time for skilled players that don't get downed, creates bad incentives to be downed, and has a negligible effect even when you are downed.
As for Radiant Retaliation, retaliation does very little damage overall and given the sources of damage for guardians, you would presumably have very little condition damage as well. I'm assuming the entire point of you taking this trait is to increase your damage, but let the math stand that Right Hand Strength provides magnitudes more damage than the poor scaling of retaliation's already poor base damage.
Finally, it should be stated that condition damage simply doesn't scale well on guardian because guardian has very little outlets to apply condition damage (no bleeds, no poison, no torment, no confusion). Because burning doesn't stack in intensity, the damage that burning can apply is extremely limited. Trading off going power for condition damage has no upsides because you aren't any safer either, you simply do less damage. So I would recommend changing both traits in the Virtues line as well.
