I think he's talking about the way dice rolls can totally screw you, at random, no warning.
Take, for example, a recent game of MOM I was playing. I had a hero, buffed to the max, who could take on entire armies if he wanted to. He wiped army after army after army of mixed paladins, priests, magicians, and more off the map.
But by pure chance, a mere pikeman who got an 'iron skin' buff took him out in one shot. One shotted a hero who could, more often than not, one shot anything that attacked him. (Note: For the purpose of making a point, I'm ignoring a rather nasty bug where said hero somehow 'lost' the ability to attack... apparently there was a rap-around error where over-buffing left him unable to attack, only counter-attack when someone else attacked him.)
At least that pikeman got to be the hero for once 
"You cannot best me," laughed the hero as he unmounted his horse, and made his way over to only other living thing on the charred battlefield. The lone pikeman, while injured, saw his advance and pulled himself off the ground and leaned against his pike for support.
"I'll tell you what, I'll give you one free shot, I won't even flinch," the hero boomed, his arms outstretched and his voice echoing over the now silent world, "you are barely more than a mere peasant."
The pikeman gritted his teeth, and with a second wind, launched himself at the hero. With a scream, he charged and closed his eyes for fear had gotten the best of him. He felt resistance, and he stumbled, and when he opened his eyes he saw nothing but darkness. "I must be dying," the pikeman thought to himself. But slowly the world came to, and looking up from the ground the pikman saw the hero, arms still outstretched, eyes to the sky, and against all odds his pike.. thrust through the hero's golden breastplate. "It's finally over," the pikman smiled. "the tyranny is at an end."
Now, back on topic, I agree with Luckmann. In my opinion, I just think we need something different, and unique that is realistically based so the world can feel more alive from game to game. Whether that's a hidden tech tree, random techs, or something entirely different we can't even imagine right now is what has to be decided. I think the devs will come up with something truly great, especially with a year long beta. But the civ style way of teching has just been done to the bone and i think we need to get away from that
