Question about how bad Zoners have it has nothing to do with 4.86.
Hostility towards Zoners was known to grow in mid of the update, or new alliances were made, or non aggression pacts were forged. Yes, in 4.86 Gallia is coming out of the closet and that's officially the only new threat, but that doesn't mean that, for example, new trade route near freeport 1 will not be opened that will supply.. Lets say Rheinland from Liberty resulting in 150 zoners trading trough there daily, pissing off the Liberty and making it hostile to zoners!?:D
