Requiem: Bloodymare has recently opened up a pretty cool new feature: Server vs. Server battlefield. If you’ve played WoW, think about Alterac Valley a bit — it’s pretty close, except instead of having to kill NPCs to win, you have to control points on the map and rack up points. The other difference is that this battlefield is open to anyone on the server, regardless of level. I wouldn’t recommend entering at the lower levels, however. (I did just to get some screen shots and a post)
The servers that are pitted against each other are Hammerine the PvP server and the two PvE servers Valdes and Lintra. (the two PvE against the single PvP) Even though it is outnumbered, Hammerine has so far taken most, if not all, of the battlefield victories.

Running around, trying not to die...
The battlefield opens three days a week, twice a day. The days are Wednesday, Friday, and Saturday. The times are 10:00 AM PST and 5:00 PM PST.
The battlefield itself is pretty empty and wide open. There are ruins of an ancient temple towards the mid-eastern side of the map. There are five points to capture. Winning conditions are to reach 2000 points first, or highest point team at the end of half an hour.
I’ve managed to participate twice so far, both times under level 20. (you get one-shot a lot, it’s really not worth it) The lag is fairly bad when everyone is grouped and fighting, but that could easily be my system or some other problems. In any case, if you don’t have a higher end system you’ll likely experience a nice slide-show when both sides bunch up and duke it out.
As far as fun goes, the potential is there. Once I’m higher up and replaced my system I’ll give it another shot and post my views of it then.
