Siege of Mirkwood Patch 1 is now available for testing on the Bullroarer test server, so be sure to log on if you'd like to check out the changes before they go live in Lord of the Rings Online. The preliminary patch notes can be found after the jump, but keep in mind they're a work in progress and could change before the patch is approved.
In addition, Turbine has announced that it is "aware of an exploit that can allow a player to acquire more skirmish marks than intended. This issue is very easy to track, and any player found using the exploit will have their account immediately banned without appeal." Keep that in mind if you happen to come accross the exploit.
