Dunno for sure, as I haven't flown much the last couple of days, but I have a pretty sound idea why....
Blood frenzy among my fellow knights and severe episodes of acute loss of TEAM thinking.
I logged in today for a few sorties. Knights had almost fully 2 of the 3 "slices". A huge green blob of dots was struggling to take bases up north from the rooks, while a small handfull of bishops were taking Southern fields almost at will. Despite several calls for help that were ignored, myself, Crusadr, and one or two others I don't recall names of were the only ones resisting. I personally downed 3 fighters and a C47 before finally going down for the first time, and by the time I could re-up, another load of goons showed up and the field was lost. This scenario repeated at least 3 times while I was still on. They were taking fields using only 3 or 4 fighters and a bus full of goons. I made one more frantic call, asking, and I quote, for just "10 guys from the spastic horde up north to come down and we could repel all the bish attacks." I finally got a response, but it was some unfortunate twit that figured it was more important to critique my diplomacy skills than to come down and see if he could help. After field 177 went down the same way as the others, someone at 199 called for help. Rather than talk crap to him, I responded, and he and I and a couple of others held out as long as we could, but without just a small group of additional guys to help, we couldn't hold out forever. I finally decided it was pointless to keep it up, and logged. When I came to the BBS, I wasn't at all surprised to see this thread. Sad part is, I just logged back on to AH for a sec to check, and in the time it took me to type this post and get a cold drink, my fellow Knights had lost fully half of the south eastern "slice", mostly I suspect to the very efficient and virtually unopposed "commando raids" performed by the bishops. Just my two cents, but it definitely seems we knights totally lose sight of working as a team at times... lack of response to requests for aid, even when strategically obvious and important, lack of 6 calls when there are 4 friendlies behind the guy who is on your 6, etc., etc. With just a little coordination or team thinking it appeared to me we could have at least maintained our territorial holdings, and as we were gaining ground slowly in the north, maybe even dominated to the point of forcing the reset.. dunno. Sure would have been nice to test my theory though.
