I am not the most active DH there is, but this is my take on strafe;
#1 Strafe inherently sucks, lacking the raw aoe power that pretty much is needed for "efficient" farming. This can however be psuedo-fixed with rockets.
#2 Strafe owns, you can constanly be shooting and moving, and there are several skills that can be used "in strafe" - this needs to be exploited to it's fullest.
#3 It is fun
Rockets/Sentries somewhat make up for the lack of aoe capability by just pouring out projectiles at a multitude of targets all the time. Basicly you're attack between 1-6 targets at any given time with two sentries.
For changes: Prep away when you have enough hatred reg/pu radius. Maybe caltrops in for the tort ground thing or fan of knives with aura rune.
edit1: of course i run the templar for extra hatred regen; this build cleans up pretty well in mp1 with only ~60k damage (my dh is balls), windforce knockback + strafe = very safe guy no need for escapes most of the time, and when a time like that occurs. just gloom your way outta there.
