I don't know if that is true about rampage (it might be I'm not sure).
But Point Blank AE's are not centered on the target, targeted AE's are.
For example, here's two random spells I found that had those target types..
PB AE means the radius is from the center of the mob.

Targeted AE means that the radius is from the person that the ability is used on, which 9 times out of 10 is the MT.
This is why I used to harp on about aggro on some encounters. It doesn't matter if "I only took aggro for a second" because if you caused the mob to AE you instead of the MT, in some cases you just got *ALL* the DPS ae'd, as a lot of targeted AE's have small range.

That is my understanding of it at least.
