It's always been a bit hard on Warhammer Online that up until now, RvR never netted you a viable weapon as a reward. There were reasons given, of course, but in order to get a decent weapon you had to take part in different activities. For a game where on of the major draws is PvP, it seems like a rather egregious oversight. Clearly, the developers ultimately agreed, hence the new Scenario rewards including RvR weapons in the upcoming patch 1.3.4.
Item developer Sean Bosshardt put together a new developer diary to help explain the purchasing system, the philosophies in operation, and how the team dealt with balance concerns.
