I have mixed feeling on this. A downed character is not necessarily dead so helping them up is useful if they have an ability to defeat an enemy. I don't help a downed character if an enemy with more than a quarter of like is next to them. I try to take them out first. I feel like revivify should bring back a character at full health instead of a quarter health. Helping a downed character can be useful depending when is their turn and if a enemy has low health.
