both civs have huge spikes of power for all-in and cheese attacks.
Sicilian with 6 tcs? here take 42 sergeants.
Burgundi with 110 villagers?now they are a heavy militia.
Vineyards: take this 3k of gold if you are starving in late game.
those mechanics are different, but are extremely hard to balance. An even then they are not funny. Minion masters is a tug of war mostly based in luck and pretty casual, so the huge spike of power finishing games is not a big deal. On the other hand in AoE2 it will make the games lineal and repetitive.
I really dislike this design approach, and we will see in february a flood of complains about those 2 civilizations.
