I spend 12 of the last 24 hours bombing the strats systematically and I have to say: It seems they are working now as intended. So far I could not reproduce the glitch I mentioned earlier, so it remains a mystery... for now.
For example today I first bombed the city down to 32%, then did a follow up attack on the ammo factory bringing it down to 28%. The damage to the ammo factory remained for 2 hours, and it had notable impact on the downtime of ords of the few rook bases that had their ords porked around the same time - it seemed that they stayed down for about 1.5-2 hours too, instead of the standard 45 minutes.
So while playing the strategic card is still not an use of 'resources" as 'efficient' as the standard basegrab missions, it
does give bomber pilots looking for something else than the usual "fly one sector, drop hangars" routine a viable target. In fact, when I alone was able to keep one factory down for some time, just two or three player coordinating their attacks could make a much quicker, and more lasting impact. Especially on a map like Ozkansas, where many front line fields can only be resupplied by goon and not by m3.
It only takes three good B-29 sorties to smash the city and one factory, even just two sorties can make a big impact while a third player starts porking the enemy bases. So if only 3 (able!) out of 60-150 players would do the strat thing at any given time, it
could have a notable effect. I have to say this is the first time ever in my AH career that I regret not having any henchmen, err squaddies...
But I have no illusions. We are so much being used that "strats are not worth it" that we won't see much activity in that direction. The occasional strat raider will drop his bombs all over the factories with no lasting impact, and the even rarer strat missions will do the same with even less efficiency. When I called out the state of the ammo factory and that porking the enemy island bases NOW will keep ords down for almost 2 hours, nobody cared. Not even the airmchair generals who constantly complain that we "aren't fighting as a team" or "when will we learn to PORK".
