Server checks your position every .3 seconds, so basically if it updates at an unfortunate time (say, like right before you're about to exit the area), you're pretty much bound to be hit and there's nothing you can do about it. Some telegraphs are more lenient than others by having a longer cast time, and for those this is a none issue. On the other hand you have some telegraphs that happen so quickly that you sometimes even get hit even if you're moving as it targets you, and that's honestly beyond silly as in this example both reaction and response times is a none factor.
