From the little research I've done, it seems the answer is no. Could anyone confirm?
I've been playing Warhammer for a few weeks now and it reminded me how much I don't enjoy open world RvR, at least 2 faction RvR with no efficient balance mechanic.
Open world fights almost always go the same way: one faction face rolls the other over some objective, the face rolled faction gives up and the face rollers end up fighting against doors and PvE mobs.
Long story short, I realized I only enjoy MMO PvP when there are systems in place that force even sides, like in battle grounds. Doesn't matter the scale, it can be small or large but the sides must be even.
CU will be a 3 faction game and it's commonly accepted that these types of PvP environments tend to self regulate population balance. I wouldn't know, I've never played a 3 faction RvR game.
So my next question is will CU only count on this 3 faction self regulation or will there be systems in place to force (not encourage) some sort of faction balance in the open world ?
