Hallowed Ground does indeed have a delay, but what's really spiteful is that it can go onto CD, and then you die anyways because the CD starts when you pop it NOT when it starts working. This is so goddamned aggravating. Either make HG pop instantly, or make the CD only start when it actually goes off. Right now you hit HG, it goes on CD, you're still vulnerable for about 2-3 seconds, THEN it starts working. It's literally the worst "OH SHIT" button ever made because you actually have to predict the future and use it before you get to "OH SHIT" and even then you might die and you've wasted it because it's on CD and you died anyways!
