There are speedrun strategies for Way Home, and they can be further improved by killing RegLightning without resurrection and the lightning amulet; then, we can buy his stat boost and won't have to waste enchantments. But this all depends on a lot of luck. I also saw a tempo run by a Korean player on heroes2.com, but that site seems to be down and won't load.
What's the point of this? You still need to take resurrection eventually, so why not take it earlier and avoid losing your army? Maybe you can kill him earlier, but overall, this will likely have a negative impact on the speedrun.
