One difference that stands out for me is not the horde, but what the horde does. Each country has one, but unfortunately they rarely meet. For some reason the idea of a good fight is no longer uppermost in many players minds' and an overwhelming force against a weak/ non-existant foe is favourable.
MA play often reminds me of dogs fighting over scraps.
However, it is understandable. In a lethal environment there is greater saftey in numbers. No matter that it's a game, guys just don't want to get shot down. Unfortunately this leads to developing survival rather than fighting skills (which I'm under the impression this game is all about).
So here's the thing - how can MA be evolve to encourage/reward fighting.
A couple of weeks ago the hordes did meet (bish/nit I think) in OZ resulting in a cat5 furball and one of the greatest fights I've been since AH2 realeased. More please.
