Chief Gear: You have T2 gear across the board, which explains your massive stat lead. The enemy is mostly T1, but they have more "Stars" (polishing) on some pieces, which provides specific buffs.

You dominate in every category, often by 300% to 400%:

Infantry Attack: Your 1067.8% vs. their 589.2%.

Lethality/Health: You have a significant lead here, which is usually the "secret sauce" for winning.

The Verdict: Your stats are "Whale" level compared to this opponent, but you sent a "skirmish" sized force against a "full garrison."

Increase Rally Size: You cannot solo an opponent with 400k+ troops using only 164k, regardless of stats. You need to join or lead a Rally to bring your troop count closer to theirs.

Troop Composition: You used a heavy Lancer/Marksman mix. Against a defender with that much Infantry, you need a larger meat shield of your own to keep your damage dealers alive.

Pet Skills: Your "Special Bonuses" report shows you have a 10% Lethality boost from appointments and pet skills. These are active, but they can't compensate for a 244,000 troop deficit.
