Hey Leong!
We missed you at the last battleday.
Requiring a longer sustained hit makes sense of the lag shot and making it hard to hit.
We did not notice much of an issue with the 3m defense-distance.
I also don't think it pauses when hit.
As indicated by the OP, the suspension does sag when it starts and stops.
I liked the way it looked as it appeared to throw it's weight around like the real thing.
But I can't speak to how it handled.
