Guild Wars 2

The skill clearly says “revives fallen allies”
and not "will heal up allies in an attempt to instantly revive them, but will fail due to poison applied on the downed enemy with low health’

For an elite skill, it should be guaranteed that the downed ally revives from it.
Can’t you just change the skill that instead of healing the ally for a huge amount, you just trigger the ‘revived’ action?

it’s been 3 years … Thanks !

Battle Standard has always worked like this and as far as I know it is the intended behavior. Agony and poison reduce healing power and thus make it not revive.

If you take a look at how downstate works in general, Vapor Form for example. You will notice that in the combat log it says “Vapor Form heals you for x” and “Vapor Form hits you for x” the same is the case with Vengeance on warrior. When you consider this, this is no “revive button”. You get in and out of downstate by healing and damage this is how the mechanics of the game work and how skills work in general. Battle Standard works like this and I believe the other class revive skills as well. That said, they could make it heal for 33% more while under poison or agony if this is not intended.

From the wiki: Poison and Agony’s healing reduction is effective on downed allies, making it take longer to revive them. They can also cause revival skills to not fully revive an ally.

Or they might just changed the description to conform with the actual behavior, i.e. don’t be so sure it’s a bug.
