Hmmz, been a few days since I played. Took a couple of days out for WotLK and work has prevented further play last few days. (I like decent focus so a few mins here or there doesn't do it for me).
Last time I did play openfield RvR, Order were in much larger numbers than us and were kicking our asses all over Praag, at one point prime time the ratio being around 3:1 in Order's favour in the zone.
What I have noticed however is that once Order start to lose they are suddenly nowhere to be seen.
There was well over 50 Order in Kadrin valley last night at 8:30 they took both keeps and all Bo's in about 10 minutes.
Both realms can now throw out equal number, its a matter of which side starts to lose players first after suffering a defeat or two.
