Sorry for the English, because i also don't speak french
I am the russian ork player, that played against Mani. Everything in your post is true, except for the fact, that if game continued naturally, Mani would be tabled on turn 4. On my 3rd turn i only rushed for objectives, without shooting SSAG and 13 smashas at his characters. I'd like to see how he was expecting to fight me off with one wyvern and couple useless characters like Harker or astropath, that might have survived my round of shooting.
Mani was really good opponent, i'd like to play more against him or your team next year!
