I see it all the time as well. I'm not sure it's terribly useful but I do notice it when it happens.
Something you've likely not seen, however, as it requires a silly investment of CP (but I wanted to test it out) is the shield when drinking a potion, the startlingly weak and ephemeral shield when blocking (which lasts longer than the orb it creates, with a flapping-wings like afterglow) and the "go invisible after killing something with a heavy attack) which absolutely does not have to be a fully charged heavy attack.
