So what I have noticed being an issue with nations, many players who's focus is PvP end up "suffering" because the server lacks some form of casual daily PvP.
I have invited many people into my town in the past year and I noticed that there is a special "type" of player that just gets a full set of gear, and goes around hunting people, and most often Nations shows itself to be unsuitable for their goals, and they end up leaving and playing on other servers and only logging for sieges at weekends.
Assaults partially solve this problem but they are still "scheduled" and happen not-so-often and what i think the Nations needs is a place where you can just log in, and go there to PvP for some time whenever you feel like it.
So I came up with two ways that I think this could be handled.
1. "Better" bounties.
Basically issue with bounties as of now is that you don't really have a reliable way of knowing if you will be able to kill a person even if you find them. Traveling 5000+ blocks just to see that the person you are after is not leaving their claims until they log off could be very frustrating, and you are completely reliant on their mistake in order to kill them. Which most of times just means it is not worth "hunting" people because it comes down to "luck" if they gonna step out of their claims or not.
What I would do is, make it so that PvP is always enabled for people who have certain amount of bounty, for example $2000+.
That way they will always be a viable target until they end up being eventually killed.
Maybe there could be a mechanic to "bail" the bounties by paying their amount so they disappear for people who don't wanna deal with always constantly having a bounty on their head, and once either bounty is collected or "bail" is done, further bounties for same person would go on 48 hour cooldown(or longer).
2. Warfronts, (or maybe some other name, this is just the first thing that came to mind to describe it)
This would be a random chunk in the wilderness that spawns in random locations (preferably at least 10 chunks away from the nearest town) That can be captured and adds a recourse to the town's daily production.
For example, if a "Warfront" with 4000 iron 400 gold and $8000 appears in the wilderness, you would be able to stand in it and claim the set amount of resources every 20 seconds (kind of how plunder worked in N1).
So if you were to stand for 20 seconds in such "Warfront" chunk, you would get 1 gold 10 iron, and $20, with all the recourses except the money just being added to your town's claimable recourses. (which preferably couldn't be taxed or taken by occupation) and the money would go straight to your balance.
If it is mechanically difficult to realize something like that, instead it could just be chunks with money that you can "plunder" the same way as in N1
This would hopefully attract people who would try to claim those and fight around them. They shouldn't have any schedules or timers but just appear at random around the map.
