VICTORY!
He hit me this morning and managed to slip in and get a 5-minute Arena production (supplies; I was doing a DC). So I hit him back, as I've been doing every day, and nabbed 5 more FP from a TF. I was this close to sending him some smack-talk, something along the lines of, "You got a handful of supplies and I got five more of your FPs. I'll do that trade every day of the week!"
Instead, I got a message from him this afternoon: "Do you want to continue fighting?"
This, from a guy who still hasn't upgraded his defensive army of two whole spearfighters.
I'll send him a friend invite tomorrow. I have better things to do than stalk his productions all day.
