Still a horde in most peoples eyes if the bish do it, but if rooks or nits do it ...."It's A Well Planned Mission". The hordes on all sides are here to stay and if we the players dont like it, we can live with it or move on, nothing we or HT can do about it 
SMokinLoon's mission isn't a horde, I'd even go as far as 10 players in the mission as not being a horde. The mission he describes is the missions this game is missing. With the horde there is very little chance of NOT succeeding, where is the fun in that? Miss your bombing assignment, No Problem! 6 guys have the same target, just in case.
Yes all sides horde, BUT the Bish are notorious for it. It seems that it is the only way they can get anything done. I'd be willing to bet they also "win the war" most often, and I'm sure it is due to this horde style.
Can anything be done? you bet! Even the players have the control to take care of it, but they won't. All you need is for the little generals to start making better missions. Build the mission around 30 players. Use some as a bomber group to come in at alt, some as fighter cover for them, some as deackers, some as porkers for adjacent fields to kill supply runs. If you DON'T get 30 guys adjust your plan, maybe a few less fighters for cover, our have the porkers do both bases in stead of using two teams. The point is the "leaders" have the control and can control the hordes, but they won't.
Today's players are too tied up in the win the war at all costs, because after all there really isn't any cost right? That is where HTC could make their changes and make it "cost" something.
Would it be better for the game? I don't know, but I think it would. I know I would spend more time in missions if there was a purpose other than being one of 30 guys to take a port

Defending would be more fun as you and the other 5-6 guy who upped might have a chance to defend as opposed to just padding some dweebs score.
