What is the general opinion on the war bonds scene

I have a general positive view of war bonds, as they allow me to do small premium actions like heal troops and speed up production without spending gold. I usually use them to increase the morale of my core cities on day 1 or 2 as well as to heal large unit stacks in the late game. I can also use them to reveal local armies. There are some downsides, like a player can bring an almost destroyed stack back to full health, but I think the positives of war bonds outweigh the negatives.

What does everyone else think?
