Is it me, or do those Riders of Rohan actually look nothing like the Riders of Rohan? I haven't played LOTR Online despite being a huge LOTR fan, because I've never found a Mumorpuger that I liked. But this trailer just doesn't make it look like it has anything to do with the licence. Existing players feel free to correct me if I'm wrong on that.
I think those are supposed to be players demonstrating the new horseback combat feature, not the actual Riders of Rohan.
