This revelation invalidates all we know of Protoss society. The Protoss live for glory, and honor. They are a race of warriors. They are all prepared to give their lives for Aiur, they say so themselves. Now it seems that every Zealot we thought died honorably defending Aiur, instead teleported away to survive. Avoiding death by using teleportation? That is cowardly, the Protoss face death with honor. Everything we've seen about them in game shows that the Protoss value dying in battle like a warrior should. Now, they do not die, they flee. And they are reconstructed in Dragoon walkers. The existence of a Dragoon must be one of torment, for the warrior inside to know he fought hard but still failed, and is forced to use machinery to continue the battle. Why would any Protoss want to continue living in such a state? Simple: they don't. Why do the Zealots and the Templar flee like cowards when the battle is too great? Live a coward's life or die a warrior's death. Which do you believe the Protoss would choose?
In closing, in StarCraft, the Protoss had a battle cry;
"My life to Aiur!"
Now it seems that this quote needs to be restructured to suit what we now know about the Zealot. So the new Zealot battle cry is:
"My life for Aiur, unless I'm actually about to die, in which case I'll teleport away to be revived as a robot."
