Its game mechanics because it occurs in the game outside a cutscene, what other evidence is needed, thats the definition of game mechanics.
Except you have to prove it is limited by game mechanics. It's not actually something that occurs in gameplay.
What does it matter if the Predator tanked the lightning in the first place? I don't see how that matters at all in this debate
Um, what? It does matter.
Elites don't use weapons that electrocute you.
Wrong. The electrocution comes from the voltage, which is what Covenant plasma bolts have. They generate 100,000-150,000 volts at .2-.3 amperes per second, or 20-45 kilowatts. A lightning strike generally has millions of volts at millions of amperes, or terawatts. That means that the bolt itself has megajoules of energy, most of which that doesn't go into its target. If both were to go through the heart, then it would get zapped.
