Thrue, i've been beaten too by HPB's and i'm not ashamed of it.
I read the zp discussion for a while (other tpoic) and onlything that came up to me is, that is doesn't matter what ping you got.
I've you'r good, you'll win, no matter what ping you got (ok there are exceptions, >1000 ping is impossible to play).
I've got cable, and a avarage ping of 30 to 50, but there are day's that my ping goes up over 300 to 400, and still manage to win those games.
But when i've got 40 to 50 and my opponents have 300 to 500, it rather difficult to hit them, course of the irratic movement.
Also killing an HPB is sometimes impossible, i'll play much instagib, and see sometimes a stupid lamer who doesnt seem to notice me, easy target he, wel no the **** got a 300+ ping and a point blanc shot ON HIS BODY hit's and no kill, he turn around, doesn't shoot (so it look to me) and i'm a gonner.
So in my opionion the LPB is the one with dissadvantage (seems stupid but happens often).
