Are you always looking to the bars? I don't think so, and I don't think that it bother anyway, I was playing yesterday and while attacking, I looked to my enemies, I didn't focus on the bars, only when it was all quiet.
The bars are small enough to don't bother while playing & aiming, and big enough to be seen, and they are close because just looking to a point you must be able to know how well are you going...
