There are a lot of animations that are overused, but I see what you're saying with the attack animations. QoP has a reasonably fast missile speed though, so if her attack animation were to change it might look weird.
Oh, and does anyone play on THR? It's a system of bots that host games on bnet, and I must say that the playerbase are a clear cut above your average bnet pubber. The cool thing is that everything is tracked so you can see how good you did in your prior games and what you need to improve on. However, people are still semi-pubs, so don't count on your team mates like you would your friends. You'll still get feeders etc, even in tier 2.
