I used memory blur for the first time last night and I have some questions.

My party and I decided to try and tackle a hill giant. With all of us having
SoW and me having Memory Blur (MB) we didn't think we'd have a problem, even
though we are all low-mid 20's. Well, we couldn't touch that hill giant with
spells even after my tashani. The tank was hysterical and wouldn't run close
enough for me to get off a MB to get the giant off him. In the end, everyone
but me zoned, so the hill giant comes straight for me. I start pushing the
MB key... Target out of range!... Target out of range!... You begin to cast
a spell.... A hill giant blinks. The hill giant then changed direction and
went about his merry way. Cool!

Now that we know we can't take a hill giant, and bolstered by our experience
with the hill giant (noone died), we decided to try a griffon. This one
didn't go nearly as well. The griffon turned out to be just as magic
resistant as the hill giant, and a LOT faster. After unsuccessfully trying
our spells, the call went out for MB. The tank ran the griff near me and I
cast MB. A griffon blinks. Problem was, it kept chasing the tank! The tank
didn't like that news so he kept running for the zone. I chased him a bit to
try and get another cast of MB off. I guess at that point I was closer to
the griffon than the tank because it turned for me.

You begin to cast a spell.
A griffon claws you for 96 points of damage!
A griffon claws you for 96 points of damage!
A griffon kicks you for 34 points of damage!
You keep your concentration and finish the spell! (don't know how...)
A griffin blinks.
A griffon claws you for 78 points of damage!
A griffon claws you for 89 points of damage!
A griffon bashes you for 28 points of damage!
You are stunned!
You cannot cast spells while stunned!
You cannot cast spells while stunned!
You cannot cast spells while stunned!
You cannot cast spells while stunned!
A griffin claws you for 56 points of damage!
A griffon kicks you for 32 points of damage!
You have been slain by a griffon!

The question I have is, what is the correct way to use MB? Apparently, it
wipes the hate list, but if you are in the critter's aggro radius the
critter will just jump you again. Anyone have any strategies to share in
using Memory Blur?
