For Battles... a couple things - They last 5 rounds, which nets the total attack and defense, per round. That's why your 10 knifers vs the 5 knifers was a draw. Now if both sides have troops remaining after 5 rounds, that would also end in a draw.

As an example:
-- Round 1 starts

• Your 10 knifers attack with a total of +120
• Enemy's 5 knifers attack with a total of +60
• Your 10 knifers take 60 total damage (but they only have a total of 50 health, so they all die)
• Your enemy's 5 knifers take 120 total damage (but they only have a total of 25 health, so they all die)
  -- Fight ended in round 1 with a Draw because all soldiers died.

As far as the time to Battle goes... each troop has a speed associated with them. That speed has a direct influence on how long it takes for the battle to start. So if you sent only Ninjas into attack, it would only be a 5 minute wait instead of a 15 minute wait.

I'm 100% on board with all of your ideas on how to bring in some more money for payouts. Great vid!
