I've never hard targeted hit a straffer yet. Heck, at distance, I've not even hit a walker unless it was walking towards me instead of perpendicular.
They did talk during the state of the game that they'd be doing a review of ranged combat in the game, so I've been making a list of issues and suggestions to make it more fun.
I know that the devs HATE and probably will refuse to EVER increase rate of fire, so I just give up on that one, but there are several other issues. At least Phax stated that the "point blank"/"in face" issue is taken care of. That effected any form of range, spells included.
I think I've done it about twenty times total out of about a million arrows shot so far, so I'm not surprised. Times I know I have done it for sure was ranging the Drow Scorpion on Assassin's Roost in the desert. You actually have to physically lead track the target to have any hope at all.
