Why do archers not attack first before Melee Troops?

[Sponge251]

Given that archers are ranged troops shouldn't they attack advancing Melee troops prior to the engagment with my troops? This would have an effect on the outcome of the battle.

Given the expense of the Archers I would suggest this change.

Just an idea

I had an idea to allow troops to change their tactics by researching new abilities for troops from a research building as shown here
