No. siege stats should not be recorded. KDR means nothing in siege, instead people focus on capturing the flag. That is the point.
DON'T YOU DARE HAVE SIEGE KDR RECORDED
I agree.
Also, siege is SO MUCH EASIER to rack up kills. On most my characters when they are in their effective levels, I can usually pull about a 1.2 or 1.3 kdr with 30k worth of gear in battle. On siege that number is typically doubled... and lordly lord does it shoot up when I use my "eh! I got money to burn!" gear.
I've also seen players go insanely high numbers like 122-8. It would make battle stats meaningless.
KDR is a signifier in battle success. it matters there, as high KDR = higher win rate.
It really doesn't tell the whole story. If you have a 3:1 KDR, you're probably doing well. But if you just ride over to their spawn and kill 3 AFKs every round and then die to a peasant with a pitchfork, you aren't doing your team any good. On the other hand, an archer might do an amazing job of taking out horses, stunning enemies fighting the archer's comrades, and not get a single kill the entire round... while simultaneously being one of the key factors for success.
