Folks, let me explain the context of the end-of-frame ruckus. I hope that folks on each side can see the context and find it in them not to get too wrapped up in the end of frame 4.
In terms of points and outcome of the scenario, frame 4 was decided at the 1 hour mark when the allies sank the Shoho. At that point, both the Shoho and Shokaku were sunk, and the Port Moresby invasion was denied. Even if the IJN sank both the Yorktown and Lexington, it would not change the outcome from being an allied strategic and full tactical victory.
Also, at this point, the IJN had not yet found any US CV's, and the destroyers (remnants of c34 or c35) were right up on the last IJN carrier. This is not illegal -- the rules do not prohibit it at all (more on rules thoughts later). But it was so close that planes on final approach and right on takeoff were being fired on by ack from the destroyers. IJN pilots shot out all of the ack on all of the destroyers, but that left the indestructible puffy ack still going.
I know and you know that puffy ack is more of an annoyance in this scenario since lethality is turned down. But it is hugely annoying when you are trying to land or take off, and IJN planes are more vulnerable to critical ack damage, even at low lethality.
Another half hour went by, the IJN still hadn't found US cv's, IJN pilots still had nothing to go attack, the frame was already long since decided on point measures, puffy ack was still pounding away at anyone around our one remaining cv, and I started seeing angry comments by players on ch 2 radio saying they were logging and not coming back because of the *%$$^&% puffy ack.
Since the IJN started with 18 fewer players than the allies (a bunch of IJN pilots clearly didn't bother to show up), I sent a PM to Oneway explaining that all ack was shot out on those DD's and only puffy was left -- could I destroy the DD's? He graciously agreed to let me do that. I destroyed all the DD's and then checked if that got rid of the puffy ack. It didn't. (In AH, a TG with all sunk ships will still send up puffy ack -- it's a game mechanics thing -- but I wasn't positive on that until I checked.) I explained this aspect to Oneway and he further graciously agreed to back the task group off.
Meanwhile, with nothing else to go attack, some frustrated IJN pilots were taking out buildings at 63, deciding that they'd go capture it. Like DD near CV's, this is not prohibited by the rules (and again more on rules later). It doesn't add any points, and it does use up aircraft that otherwise could be searching, protecting the remaining CV, or being ready in case we find the enemy CV, but it's not prohibited.
Finally, at the 1.5 hour mark, we found the US cv's. At this point, though, the IJN was very low on numbers. We tried to get together a strike force to go hit a US cv. While we were doing that, a US strike came in and sank the Zuikaku, last of the IJN carriers. We had a very hard time getting a handful of pilots to join our one shot at a strike. We spent half an hour and got 1 scout, 2 Zeros and about 5 D3A's to a group of about 8 B5N's in our daring band. None of us expected that to get through to two US cv's, with radar up and F4F's about, but as representatives of the Emperor, we felt it our duty to try. We, um, didn't make it. Just as bad, I was on that strike and didn't even once yell "Banzai!" while tangling with the F4F's.
By then, the base capture folks had taken 30.
Right after I was down, I PM'ed Wurzel, asking him if we could we call it early -- that was our last shot at a strike. He agreed. I PM'ed Oneway and told him that the allies had the win fully in the bag and if he'd be OK calling it early. He said OK after a final TBM strike. I waited for them to sink the cruiser they were after, then called "end of hostilities".
In the meantime, the capture folks did take p13. I thought it was obvious that it didn't at all count, as Shoho was long since dead and as I PM'ed Oneway and told him the allies had it all sewn up.
What I didn't realize is that some folks were very agitated, thinking that p13 capture did matter or that the other base captures mattered in points (which they absolutely do not).
I understand folks' irritation at hostilities not ending at my "end hostilities" call. I repeated my calls. I also made it clear that Team Alpha could take as much time as it wanted to land, and I did finally (after finishing being distracted by all the PM's I got with people swearing at me) get around to setting all coastal bases to bish ownership once I realized there were still IJN at a3. For good measure, I gave the allies some extra points in case any of their planes were shot down after "end hostilities".
So, that's the scoop. There were no conspiracies by me or rules violations (as far as I see) by the CO's.
