For F2P, troop conservation usually beats a minor victory, and a modest daily routine compounds faster than marathon sessions. Fighting is expensive; discipline is free.
The same principle governs both paths — finish one thing completely before starting the next — but the portfolios differ:
F2P: concentrate Gold Heads on one cornerstone plus a universal deputy (Vercingetorix + Philip II), lean on evergreen Epics and free Legendaries, and run multiple farms. The cost is time and discipline, not money.
Spender: build four to six specialised marches for the Season of Conquest, prioritising Primes and version-resistant picks plus gear and troop tiers — timed to Recharge-Reward events.
“Finish one thing completely before starting the next.” Most new-player mistakes are violations of that single rule.
