Granted, this is not a cosmetic post -but I had to share this.
Massively Joystiq just recently came out with an article detailing the mount customization we are going to be seeing with the Riders of Rohan expansion, coming out this September. It also gives us more insight on the mounted combat mechanics, as well as additional sneak peaks of the general Rohan landscape.
You can read the article in length here.
I was excited when I first heard Turbine was going to do something new with our mounts - but now that I've actually seen it . . . I'M SO FREAKING EXCITED! This is going to take cosmetics to a whole new level for everyone who enjoys that particular aspect of lotro. Just a couple more months, I keep telling myself :)
Keep up the awesome work, Turbine! Hopefully we'll see more as the weeks go by.
