Yes I too have seen this, if a player is not “fallen” but is “downed” they get back up, however if they have “fallen” meaning they are dead it doesn’t revive them. If this is it’s nature then it needs to be rewritten with proper wording.
Another fail on this is the summon speed as with the small circle it has on it and getting it aligned usually puts you in danger’s way having it take so long to summon you are usually being burned down before you can summon the standard.
Reviving doesn’t work when I use it, doesn’t matter if they are downed or dead.
