I'm fighting 21 days straight, most of that time with 3 nations on me and rarely has anyone co-ordinated against me. Most attacks were at predictable times too each day. Since VE jumped on us two of their guys are having success as 20+ days in a row of getting nuked has slightly hampered my ability to respond as strong as I'd like. All the opponents I've fought were decent guys but not great co-ordinators considering they had the numbers advantage to pick and choose targets. I'd probably have to say VE are the best organised as they've got me staggered with 2 properly sized nations to do damage to me and they're the only ones who spied away any of my nukes believe it or not. Still, I suppose it's all about the individuals you come up against.
In any case, I wish all my current and past opponents well. They've all been friendly and honourable during pm's.
