Now that we have lag free server, we can start implementing PVP which should be done like this.
Main developer should order 24 new maps by artists which will then forward those maps to tactical map creators (placement of bandit camps and units in them).
Maps should be medium sized and then doubled (separate them with river, mountains or what ever) and then goal for each player / team (2, 4) is to defeat the last bandit camp.
I see PVP in this game only as CTF mode (Capture the flag) where reward for one team (1 player) will be certain amount of resources and all players get XP for the amount of units they personally killed / defeated.
When those 24 maps are done, at the end of each month - one map is then released and there you go, you got regular and already prepared updates for the next two years and PVP implemented.
Most, or at least, half of these maps should be made with idea that players can use camp blocking ability - better skilled player will finish faster while other one will do regular, camp by camp, battle - or lose part of his army for mistake which he did (if the player "fails" to properly block camp).
Players on these maps will have to think and act quick - there will be no time for community to release tactical map in time - by the time they did, there will be already new map /zone implemented and inserted as chance to find it with explorer.
This is basically it.
It requires 2 months of hard work for 3-5 map creators and few map artists/designers but after that, they are fully paid and you got solved a) PVP b) updates for PvP zones in the next two years. After that, there is no actual need for new maps regarding PVP. Community does the rest - releasing tactical maps and players themselves have an option: to play adventures for "safe" XP and loot or to risk little more to get, little faster, same amount of XP and loot by playing PVP zone/map/island vs other players.
I, personally, do not see how can PVP be implemented in this game if you choose other idea over this CTF style.
Thumbs up if you like it or... don't xD

p.s.
Of course, each player is limited with 3 or 4 generals (same amount).
