If they do stack, which absorb takes damage first? Is it in the order they were cast, reverse order, or divided evenly?
If they do not stack, which absorb stays on target, the first one cast, last one cast, or largest?
It seems only fair that they stack, but it also seems that this could be a pretty broken way of preventing damage. I actually haven't had the pleasure of raiding with both a paladin and disc priest at the same time (10m).
