They could just remove alliances I guess. Make it so territory wars or ranked wars lock factions into only attacking each other. Also throw on a 30 day cool down period for changing factions. That would at least make wars more «casual» and possible for non-mega-alliance-factions.
The thing is ranked warring and territory wars could be the best combat «events». However mega alliances has made that kind of gameplay non accessible to most players.
I believe that the later crimes will become more and more beneficial/profitable. So the crimes to use some of the forgery items will come and probably be super profitable. If they want some people to make materials for other players and all steps of that value chain is profitable for someone then some of the top crimes must pay insane amounts. Some forgery projects cost 3m or more in mats, if that is going to be profitable then the crime to use that material must make at least 5mill.
I play vanilla wow on a server called turtlewow. It’s very good, they have added a lot of new things like new raids, dungeons, factions, balanced some classes so it’s more like a vanilla plus. I tried season of discovery but imo turtlewow is better. I think the culture of chill leveling helps keep every part of the world alive indefinetly as opposed to the crazy rush to max level that you see on official wow classic servers.
