you're up too late Trippin! go to bed! (actually, it isn't as late as I thought it was)
Anyway, ozmono, I think your 1st sentence is what most of Stardock would like to say, I know I would. That being said, I'm not sure. Its tricky to balance that with so many other variables. I mean, more of the higher quality troop is better, right!
The way it will likely work is ... More = better. But with some super high quality units (like dragons) you can't have more, so you can ONLY go with better. And if the stats match up as seen in some of the earlier dev posts, 1 dragon will be stronger than 100s of regular dudes.
