I feel that I have a really good grasp on it Reborn.
I've paid close attention to Beachhead Studio's twitter feed (they are running the Clan Wars). I didn't jot down EVERY bit of information during the first clan war but I paid close enough attention to understand how the capture points were working. I've posted a lot of information in various threads, typically the Clan Members Only threads because it involves some strategies.
I'd be happy to explain it to anyone.
Now, when you say "clan war xp per node", that causes confusion. There are capture points which contribute to your clan war total and helps you win the war. And there is bonus xp for being the leader on a node, which grants a percentage xp bonus for any games played in that mode while your clan is the leader of that node. To which are you referring?
