It's a fun game. I've put many hours into this trying to create the perfect army. There's some things I'd like to see in a future update.
1) The points have to go up to at least 1500. It's practically impossible trying to beat the campaign with an army size of 1000. And it seems as if the campaign armies have sizes of 1500 or 2000.
2) More speeds are also needed. Both 1x and 2x are slow and can be annoying when you're trying to grind for gold.
3) I'd like to have the rows be 2x5 instead of 2x6. I know that it would mess up the armies. Maybe a 6th army that's 2x5?
