Please avoid quote splitting. Quote multiple different people in different quote blocks is fine, splitting up a single quote in multiple parts to reply paragraph by paragraph isn't. It just means you add about twice as much content to your post when it could have taken half that much.

This assumption has the following components:

Each of these factors is wrong/never going to happen in real combat:
a) Bosses don't just do fixed damage, there are offhand hits (dw bosses) and extra raid damage incoming (fires, explosions, RTST, etc), bleeds, stuns (bye bye dodge), unavoidable specials, etc
Avoidance 3-shot scenario is pretty broad, since it works for any 3 avoidable hits in a row that kill you.
For example, for me it it would happen with 15-24k hits for 100%-to-0-no-healing-no-other-damage, well within most boss damage ranges. And avoidance gets better when you dip to 4-shot and higher territory, which is true for most bosses where non-melee damage is actually dangerous.
Hmm... actually, does anything other then surged no-cd Vezax can reliably two-shot you?
b) You always have tons of HoTs ticking, shields proccing, reactive healing going on. Also, not all your healers have equal reaction speed or healing opportunity. All in all, this boils down to you having a pretty big chance to not be at 100% (or 66% or 33%, if you gear for 3 hits) before the next arrives.
Exactly! And with avoidance your CHANCE of getting killing blow WHILE your healers have no opportunity to heal is reduced. When healers HAVE opportunity to heal you're not supposed to die at all.
In general, while on some fights it's an amusing mechanic to play with, don't fool yourselves in thinking that you should gear for x*FixedDamage, it just never ever plays out like this.
