Ah, okay. I see what you’re trying to say. I wasn’t even aware that wasn’t possible in the beta, I’d assumed that he just didn’t think to pounce you.
That play wouldn’t work now, again unless the monster forgot that he was able to pounce you, but I don’t understand why you think that it SHOULD be possible, or why specifically for the assault. I guess the shield being able to break/resist pounce damage is interesting, but pounce is doing exactly what it’s designed for, which is make it very very very deadly to engage with the monster one on one, and to let a monster catch you off guard alone. It is still entirely possible to make clutch plays, I’ve run away to survive on my own as the hunter many times, and once I was even able to kill him up close like you did. The key now is that since being backed into a corner would be an easy pounce target, just maintain your distance.
You have guns, they shoot stuff from afar, pounce is a short-range ability that honestly isn’t easy to use on a target that’s even trying to juke. Pounce still maintains it’s ideal use of picking off alone targets, it’s not practical to use in battle ( which would definitely be imbalanced ). All you have to do is move to the left or right, or be far enough, and it’ll miss – in other words, being in a corner would be a bad idea.
EDIT: Note that you can very clearly tell when a monster is trying to pounce, with the crouch animation. As a monster I’ve tried to pounce targets many times, going into the crouch and realizing I’ll miss, but I’m unable to cancel out of it. I’m forced to go through with the missed pounce animation, or freeze there with my hand in the hair hoping you’ll wander back into range, and THEN go through with the animation. Pretty punishing, IMO, since a hunter can easily strafe/jetpack boost when he sees the monster crouch down.
