Unbalance civ at treaty

• Charged attack from Presidential Lances is now an attack that just adds +2 AoE to what is otherwise a normal attack.
• 25% less Conqs, and Aztecs from the TP-less native alliances. That’ll keep round numbers.
• Smokeless Powder should be nerfed, half the cost for half the effect (not just for Mexico).
• Skirm combat card in age 3 now adds +10%/10%, researches Veteran Salts, and adds the big button stealth ability. (Currently +15%/15% and adds the stealth big button).
• Age 4 Skirm range card now adds +1 range, down from +2.
• Hacienda trickle rate from livestock is 10% lower. Livestock trickle is 10% lower.
• Age 5 Federal Flag card’s improvement to the damage aura is cut in half. I think the base is +10% to current stats, and I’m guessing card makes it +20%, so make it +15% with the card. That’s still huge as a Current-Stats-Upgrade.

The problem is you cant modify base upgrades without totally broke some civ basics in 1v1, the game is more or less balanced at the moment. Mexico as civ is not even the most picked nor the one with the most wins, that is still otto.
