Why merging competing cargo (Ageira White Boxes and EFL Blue Packs) with two decades old lore behind them is bad:
1. Removing RP flavor
Laws will have to be amended into very broad and flavorless writing, because EFL wanted to disrupt the market and make it available for everyone to ship, while Ageira locked it down to Ageira/DSE/US only. This makes it clear distinction in house laws (images for example): Gallia laws Liberty laws Rheinland laws Bretonia laws Kusari laws
But after merging this cargo, it will have to be under one name and unable to differentiate between what is what.
Would be similar as merging Artifacts and Cardamine under Hispanic Cargo name. Would Outcast and Corsair players be fine with it?
2. Makes it harder to balance.
Example: if Pueblo Station and Abbevile in Picardy sells the same cargo, then it the balance will be set based on who is closer to destination, not whether it is actually Ageira's or EFL's building site. For example, if Ageira/DSE/US wanted to deliver cargo to Planet Stuttgart, it takes 14 minutes. If EFL wanted the same, it's 6 minutes. With two separate cargoes, you can balance it out for each. But with merged cargo, that profit rate will be set for shorter trip.
3. It shows that long term roleplay and lore can be disregarded and further effort to improve something and build upon vanilla lore is pointless endeavor. It took a lot of effort to lobby and roleplay with houses to make restrictions in laws to match lore and it all be wiped away as per example No. 1.
