Well in addition to the new war loot and achievements the way a war is won has changed! Now its not just a matter of whoever attacks wins, its actually based on your skill points! So if your not strong enough you just end up wounding your opponent and someone else has to finish them off! so it can be up to 14 attacks needed to win a war now! at least they will last a bit longer and give you more of an opportunity to fight back, not just instantly lose because you didn't see the WAR DECLARED notice fast enough!
You can slaughter your opponent with as little as 5 attacks!
