Now that the NDA is lifted, I can tell you that WAR is the best PvP/RvR game out there, but is seriously lacking on the PvE side. I expect it will be a successful game because of that. I am not a PvP kinda fella, so I canceled my pre-order.
All the PvE content is geared to help you get into RvR. You can't even finish out your character without maxing out your RvR level. For those of you who have never played DAoC, WAR will have generic lvls, and lvls you gain in RvR sort like crafting lvls. They already stated that someone who RvR's will be more powerful than the same class/level of someone who doesn't. If you like PvP/RvR, it is a must have. If you like PvE and exploring the environment, skip it. Fell free to repost this wherever you think it fits.
P.S. I started beta in December of last year and finally figured out my input was not wanted about a month ago. I was one of the few encouraging more PvE content and discouraging the wide gap in power between the RvR and PvE people. My suggestion of grant RvR only skills to RvR ranks was shot down without a fight.
