We currently utilize a neutral NPC faction to balance fights out (on a territorial level) in LoTD, I am speaking, of course, about the neutral Tomb Prince minions. For those not in the know, when a faction controls an overwhelming majority of battlefield objectives a contigent of neutral npc will venture out and capture BOs from the winning team, so that the match is somewhat balanced.
So, taking that into consideration, I would propose utilizing a similar system to balance out the other RvR lakes as well.
AND also, a way to bring into the game a fan-favorite enemy as well: Skaven.
You could have Skaven pop out of caves (which are plentiful in RvR lakes) and move to cap out objectives in the RvR lakes after a certain level of AAO has been reached (say around 60 or 80%), which would force the faction with overwhelming numbers to confront both the diminishing numbers faction AND the NPC faction as well. That would help with both faction number imbalance and x-realming, and the time between attacks could increase the further AAO increases on one side(to the point perhaps of venturing into a keep to hamper a siege if left unchecked? I am unsure whether or not the technology is there to accomplish that).
Plus, perhaps some of the exotic items ALREADY in the game, such as skaven cloaks, skaven trophies and other exotic vouchers so one could argue it would actually take LESS work to implement this change and it could offer a more dynamic solution to empty lakes of RvR where instead of just stomping out the opposition, the team with the most numbers would have to actually contend if a challenge.
What do you think about it?
No doomsayers please, I would like to hear some open-minded opinions on this suggestion
