I just wanted to state, the sicilian donjon rush is even more broken than tower rushes were before the nerf. And it was nerfed for a reason. Why you bring back a mechanic you tried so hard to remove from the game? It makes no sense.
You don’t need villagers to build the towers. You get a (almost) free production building right next to the enemy base. Which one builds units which can defend the towers from the only things that threatens them: siege and melee units. And lastly: First Crusade gives you up to 50 free of these strong serjeants.
Don’t get me wrong. Serjeants aren’t OP by any means. They are actually the best balanced thing in the Expansion. They can be a really good front line unit in your composition. Unfortunately Sivilians don’t have a good variety of backline units. They get good scorps, but they have no good synergy with the donjons.
Also their bonus of reducing incoming bonus damage is somehow useless because they get neither good cav nor archery. These are the type of units which would benefit from the bonus. The bonus is really nice, but somehow useless because you can’t really play around it.
So, in my eyes: Nerf the donjon rush but make the civ more balanced, give them more options.
Donjons don’t fire arrows on their own, but cost 25 stone less and have +25 % hp.
They fire arrows if villagers or archers are garrisoned inside, but only according to their dps, not more.
This will balance the donjon rush, because you need to bring archers along to make the donjons fire. These archers can also complement the serjeant, which is a great frontline + raiding unit. The donjons can also work as healing platforms for damaged archers and serjeants.
Donjons could still be used very efficient as a defensive structure because of garrisoned villagers can fire arrows + they can produce their own defence against siege.
Then first crusade: Just give 5 Serjeants to each town center, castle and donjon. This would balance it somehow. Still an insane powerspike, but because Sicilians don’t have a strong eco bonus or discount, this is also a much needed powerspike. 10 to each TC is for sure OP, but 5 to each of these Structs is somehow balanced, because it takes some time to build this up, it also supplements the donjon play instead of enforcing it. And because it needs more time to build this up, the opponent can expect and preemptively react to it, going for more military which also helps against the donjon play.
Ultimately i’d like to give sicilians hussars, just to make it more viable to play around their cavalry and their reduced bonus damage. Of course this will make their trash comp very strong, but not stronger than other trash civs like byzantines, magyars, koreans or persians.
To the burgundians I have nothing to say, they are just OP atm.
