Low HP AEing

[Daldaen]

I'm curious how this functions. Don't know too many people who would risk death for me to test something myself, so I figured I'd just ask here.

My recollection of this, was that the low HP player would hold aggro for about 2~ PBAEs and then you would be forced to camp out otherwise on the 3rd one you would get killed. I'm not sure if it just so happened that the times I remember trying it on live, those specific AEs got you enough aggro to pull or that it was specific to numbers of casts?

Or does it work out that you cannot pull a train off a bard with low HP regardless of how many casts you do?
