It's been mentioned so many times already; this is an unacceptable visual bug.
Why is it that 3 weeks after the new Rift comes out that we are still seeing the visual bug where moving your camera over a teammate or opponent makes it seem as if they took damage at that moment, when it is really all the damage that they accumulated since you last saw them? There have been numerous threads already but it just doesn't seem to garner any attention at all. It is incredibly misleading and without a doubt should be your top priority of known and readily fixable bugs.
