Let me offer some thoughts on Ramp on Al'Kabor (which doesn't seem to work quite as expected in my experience with Ramping targets). This is based on experience, and a lot of documenting ramp problems.
First, the ramp order is set as people gain aggro on a target (either by initiating hate, or by generating proximity hate). This order doesn't change normally. But, a person will be removed from the hate list for any number of things including zoning out, dieing, using FD (and getting a blur), and so on. What this actually does is to open a hole in the ramp list. So if the number 2 person in the ramp list dies, everyone below number 2 doesn't move up the ramp list. It simply creates a hole there. The next new target (not already on the ramp list) that generates hate will get tagged with the highest open slot on the ramp list. This makes it SEEM like (sometimes) that dieing doesn't remove you from the ramp list. If the number 2 ramp person dies (presumably from ramp) he is out of the ramp list. If he gets resurrected in, and nothing has changed, then he now reoccupies the empty number 2 slot in the ramp list and regains ramp.
Two things will clear the ramp list entirely. Memblurring a mob will clear the ramp list. And if the mob gets stuck in the geometry (pushed into a wall or pillar or some such) and warps out, this will also clear the ramp list.
As you can see, this does interesting things to Ramp. It means that to maintain a ramp order, people who get ramp who shouldn't have it need to move out of ramp range as quickly as possible. As long as they survive, it doesn't create strangeness. Second, if you are pulling a target through a door, the door needs to remain open - or, when the mob hits the door (and warps through it), ramp gets reset and will bounce around some as people either move in and out of ramp range (or die) until ramp is established solidly.
Finally, this also means that a monk who is using FD until the get a critical success (blurs the target), will immediately move up the ramp list to the first open slot. If this is high up, on the list, the Monk can actually become ramp after a FD.
What all of this does is to suggest that ramp can be manipulated just a little bit. When the ramp tank dies (if he does die), the best thing to do is to have a pet class get a new pet - thus creating a pet RT. Also, if a non-caster class needs to get ramp to protect a bunch of cloth classes, a monk can work the FD until he gets his ramp value reset.
