Well, I got the Very Large army yesterday. First wave, 3 Lancers, 3 Jaegers, 2 Rogues, second wave 3 Jaegers, 3 Rifles, 2 Rogues, 60% bonus. Nasty. I crushed it anyway, but something like this is going to be brutal for a more peaceful player. OTOH, there is no fail penalty any more, so this helps to balance things a bit. Honestly, today's requirement of 33 4 hour productions was worse, because I have neither to time or inclination to futz around with something like that today. (I think Inno needs to tweak the supply productions a bit, especially since people are planting Blacksmiths like crazy; nothing is irritating me quite like using a Dynamic Tower use to get 1 BA good.)
I think I've said that DCs are really looking to require well-tuned cities, and that's definitely turning out to be the case. The people who seem to be stumbling the most are either planning poorly or have over specialized one trick ponies.
