What the recap tells me is that, even though a microsecond before I died I had a full healthbar plus shields to absorb damage, a single opponent in PvP that I never saw was able to instantly kill me with five attacks that can't occur simultaneously... but did.
To me the death recap is nothing more than proof of exploitation/hacking... and a reminder that ZOS does nothing about it.
An advantage of playing eight alts with different classes and skill mixes is that you recognize the various skills used to kill you... and know what the delays are between execution (if you're not cheating).
