Gaining Olive oil while gathering barriers is unrealistic. Maybe you can make one berry bush visually turn into a olive grove when a mill is build near berries. Or you can make an olive tree spawn when berries are all run out, something like that.
Where’s Olive oil in fish? there’s only fish oil in fish.
I think its better to keep olive gaining to Olive farms and trade. Maybe make something like lumber camps make spawn olive trees and when chopped gets some olives.
While unique mechanics are appreciated they need to make sense.
Nobody really even goes on water with byzantines due to how bad the dromon is, I think a lot of people have probably forgotten that they even get oil from fishing and trading.
I was gonna open post about this too.They get %50 oil from berries is non realistic but also broken.Think it like this normal villager gets 1 resource bzy villager get 1.5 resource.Then when you do the gathering upgrades normal civs get %10 of 1 while byz get %10 of 1.5.It also improves further with cistern bonus and if they have Grand Winery its broken.They have the most broken eco.They can overwhelm oppenent with numbers easly.
I recently suggested a remake of the marine system… or well, not so much a remake, but adding 2 more ships, a Boarding ship (II) and an Imperial Age anti-warship (IV).
The Dromon could then be a replacement for the Boarding ship for the Bizantines, because is a “Close combat ship” and the Byzantines could have their own ranged Springald ship, and we’d all be happy.
