Hunters are not that easy, it takes time to know when and how to do it, And also a well amount of practice if you want to do wall jump just as many of the guys know.
Experienced players should know where's the hunters spots, so if you are still getting pounce at the same spots..... dude..... why.....
Obviously new players would always be the ones who look for, but it is not just for hunters, but for chargers, smokers, jockeys, etc... A experienced player can take advantage of a new player just with a charger or a jockey.
If a 25 damage high pounce isnt that much of skill, then avoiding them needs no skill at all.
BTW: the hunter "get up" animation is tricky, someone needs to know exactly when to pounce when it is in animation, if not, you dont get it; except when you're getting up from a charger, thats when the aimbotting guys appear.
