In all honesty that was a horrible game. Both players demonstrated their lack of knowledge in how to play DeathMatch aggressively. It's an Isis vs Thor so right at the start it's not "totally" fair as Norse lose power later on.
Kirby shows a lack of skill as his he is not quick to hit Mythic and begin a Migdol immediately after Heroic. Slow micro and poor use of time is sinning in DM. No caravans are used ever in the game and his gold miners were idle for long periods. His first attacks are spamming mercs from his TC and sending them across the map. This doesn't actually do much other than annoy the opponent, only harm his gold reserve. Kirby also shows he is slow to get non-temporary troops ASAP. A crucial skill. Only using 2 Migdols the entire game.
One of the greatest flaws was when Kirby put his Titan Gate on the front line. Quite literally one of the dumbest moves ever. Sadder is that the enemy does this too. Even stranger is that Kirby actually deletes his free myth units.
"This shows that even a egyption player can beat a norse rush even when the odds are against you."
A "rush" in DM? Everyone starts attacking almost seconds apart!
Finallly, I would not consider yourself an expert or a good DM player. There are many better than you.
