The patch 1.3.0b was mostly about Combat and Career changes, i.e. CC stuff and AE fixing with a little bit of RvR stuff.
I noticed one thing that seems quiet interesting for imbalanced servers:
Fortress timers will now decrease by 15 minutes for each time the corresponding city has been contested in the past three days. The timer cannot go below 15 minutes total. For example, if Altdorf has been pushed into contested twice in the past three days, and Destruction pushes the campaign into Stonewatch, the time Destruction has to defeat the Fortress lord will be 30 minutes.
Seems like an interesting mechanic to reduce the farming of capital cities. I have no idea if it will work, but killing a fortress lord in less then 15 minutes seems like a hard task even on imbalanced servers. At least defenders have a chance to hold off an attack …
On Drakenwald this will most likely play no role as capital city attacks are rare.. the curse of somewhat balanced realms. ;)
