1. Low pop bonus makes sense to strengthen a faction with a lower number of players. However, in non-locked campaigns, people just relog to one faction to get low pop bonus and then play with their other faction. So, low pop bonus does not make sense in a non-locked campaign.
2. Score also does not make sense in a non-locked campaign. People are rewarded to manipulate the score and getting higher rewards with their main char.
Conclusion:
-> please disable low pop bonus and score in non-locked campaigns. It does not make any sense from a conceptual point of view. This measure would also reduce relogging, waiting at the base to get low pop bonus or other unpleasant behavior and make cyrodiil a lot more enjoyable.
