It would be good if NGD removes invasion (till they rework it) and add War Zone influence system.
Depending on current possessions of forts/castles in War Zone, realm benefits or get penalties for economy and xp system.
Example: Syrtis has all its forts. Prices for items in shops, as well as worth of loot, is normal, standard price. XP received by mobs is standard.
Syrtis captures enemy fort. Prices become lower for some %. XP increases slightly, for some %.
Example 2:
Syrtis lost Algaros. In that case, Syrtis has economy and xp penalty. Prices in shops go up, xp slightly decreases. Percentage that Syrtis lost by loosing its homeland fort, goes as bonus to realm that captured Algaros.
Castle is more worth than fort, and for loosing/capturing castle, realm gets bigger bonus/penalty than from fort.
Why?
Hitting on "economy" is standard option in some games, but still it won't be enough motivation to leave grind and go help recapturing fort back. But if you hit also XP, people will be more motivated to leave grind, and go help in recapturing fort.
This system would make fort wars more often, and will orient game to fort wars (like it used to be).
Picture: example of suggestion.
3 nations are displayed in bar, and their influence share in war zone.
Prices and Tax are displayed for realm where player who took this picture is.
