Hey guys - ok lets shine some light on this once and for all.
But first I did want to mention that in the coming patches we are greatly increasing the cost of stamina for unit running, as well as decreasing self-healing. This will greatly help against player who just run around and avoid battle, or heal.
Anyway - it`s a really simple stem.
You might have noticed the green/red bar on the left side of the screen. This bar shows your (green) and enemy (red) army strength for whatever units they have alive on the battle map.
And victory/defeat is declared when one player is 80% stronger than the other player.
There is also a battle timer as part of this Strength Bar. Once that timer runs out the player who has a stronger army - wins. We Might adjust this, to declare a draw - where both players will get defeat
