This recall feature is outstanding!
We can live to fight another day!
Would it possibly have any effect on ranking changes? Nothing big, but the equation evaluates it as if your ranks were closer if you recall instead of die.
This could incentivise people to not stay in a losing battle of attrition forever, or toy with people who don't know they are defeated.
Knowing that it's time to retreat is a good commander quality, and this is kinda diagetically like that.
Perhaps in ranked games there is a signal the enemy is retreating, and it takes a moment to charge.
Anyway, love the feature!
