I see nothing wrong with them proving themselves - and even then, combat school must have had similar incidents to train people with such abilities. Beacon is merely a step-up in that regard, not an instant jump from inexperienced to badass

And as far as the Grimm, they WERE a major threat before man harvested Dust, then they were slowly pushed back (via the intro from Vol. 1, Ep. 1) - now aside from the largest ones, most of them are more fodder than anything, but humans don't yet have the numbers to cleanse the world of them, so it must be done carefully.

And their Aura's? They can choose whether or not to activate those, so not every hit will be blocked... plus I presume part of Beacon training is how to get more out of their Aura with less. And we don't know how much an attack drains what amount, or if there's different rates for it - or have a complete list of what does drain it exactly. But even with all that, I don't think injuries are a natural part of combat in RWBY in the first place, due to their Auras
