Twice today I've placed my Battle Standard directly on top of a downed ally. Not beside them, not behind them. Dead smack center of them. I use ground target on target. In both of these instances, the battle standard did not revive my ally. The player was down for roughly 2-3 seconds (i always pop quickness when dropping my battle standard, so it gets placed quickly.), but when the battle standard landed, they were not revived. I was then called out for not knowing how the elite works.
Can someone please explain to me why battle standard did not revive? Other players were saying that battle standard cannot revive an ally if they have "x" stacks of poison, or if they are below a % of hp. However, I have never had this issue before. In certain cases I will also pre-cast the battle standard (if i know my ally will be downed before the animation goes off).
