Brian, keep in mind in your last photo posted that your legs are very close together. with your thighs and armour on, you will be standing a bit more wide and it doesn't seem as wonky.
I don't mind the minor cracks, one was easily fixed with that T-shirt/crazy glue trick, plus, it adds a little character. The other area that cracked likely would have cracked with a rivet too assuming it was meant to be riveted and be aligned on the sides. the stress point presented itself during install, not through wearing it.
