It's impossible to use the OP's scenario to determine whether or not the HB is OP. While I'm sure the OP knows his capability, most of us do, but without also having supernatural mind power there's just no real way of being sure that the other player's reflexes weren't better...at least not without also having the ability to correctly pick this week's powerball numbers.
I definitely get what the OP is saying, but it just doesn't work that way.
