No, dude, you didn't get it. Ment was talking about the "enchanted ballista" and "empathy" skills, and the Necropolis, as I understand it, just happened to be available. But your replay with Chaos, where you remembered to equip the Necropolis hero with a Dwarven set but forgot to give Winged Lord the "Master of Chaos" skill, was completely irrelevant. And even if it were relevant, it still wouldn't prove anything, because the situation in it is unrealistic.
The "enchanted ballista" in the real game is actually a fantasy. Firstly, because the chance of getting it is 2% (and on a mentor, you can spend 200,000 gold on it), and secondly, it's completely useless for a green hero.

Ugh, Lord. Your replay is some kind of joke, right? You might as well fight 10K neutral Druids using "subordination" :D :D
