Don t you get it? People get a 100m status boost they shouldn t have, once you attack them.
Thats not an issue? If ur total status is below 100m its less. As example, a player shown with 25m defense suddenly has 75m when younattack him, he gets a boost of 50m. This is not display glitch, its a real extra boost given out by Gree.
And btw the boost is given to you as well. Just let you attack(not raid) by someone else and show the PvP Screen, you will see the extra defense as well.
And If you fight common guilds this war, where you suddenly have no good targets anymore cause their defense went up to the roof, tell me again its no issue.
