Then why have two build queues? The question is...what were *you* doing prior to turn 50 that caused you to lose? I almost always build a basic military unit first thing to defend my capital.
***Because defending my capital city is important.***
But if you don't defend your capital, that's a ton of extra economic advantage you'll get over your competitors. For the 20% risk you'll be eliminated early, it's worth it, IMO.
And those kinds of justifications are why we need a split queue.
