We should somehow however think about how it can be made a little more even. Looking at the experience, equipment and skill level that the average player on the Liberty side brings makes me actually wonder that the difference is "only" 66 vs 17, which is rather depressing already. Seeing the outcome of the normal fight and the kill ration of 4:1 makes me expect nothing else but a one-sided frustration and as a consequence "winning-team-joining" rather fast.
In chats, the option of giving LN players a higher bounty than 5 mil bonus per kill.
It has also been mentioned to perhaps give LN players more points per kill to keep the outcome of the event a little more "open".
I am just putting this in here because the trend has been there before (in different confrontations, with different parties), and it often ended in a not-ideal way.
Perhaps there are ways to steer things from an early point on.
