actually, the best way to get many points is to hunt the other nation player. But it requires a damn good equip and very good player skills. If you don't have a godlike equip, you could try to build towers, but do it only if you know which towers on which points are useful. But simply building works only on the low wars and you need allot of money which you could spend on better equip and on high wars you'll never reach the points of player hunter.
