Here's a video that I came across of some RvR on the Genesis server, just to give people an idea of how PvP works on DAoC. This is from a Warden's perspective in the Hibernia realm (the class I'm going to main!). Some of it is in fast-forward to skip some of the slower parts I think. You may have to mute the music, I did :P
