It's more useful to use Song of Peace and sometimes Enthusiasm with Djinns.

When facing enemy Djinns, it's more effective to use other spells than Song of Peace (although sometimes it's necessary, I agree). Djinns can also cast Illusion, which will hold the enemy for a while, or they can attack with ice.

Besides, if you can hold the enemy with Djinns and maybe a Mage of Order, Life will have even more problems with that, so what will happen to the poor archers when enemies reach them... I think it's clear.

And they can also have a Mage of Order in their army - no problem. And if he's there, by the time they reach the archers, the enemies will be mostly gone - and they can finish off the remaining ones in melee combat. Besides, there are also angel guys who will try to eliminate the most problematic units as quickly as possible with their wings. Well, even then, it's not exactly an archer army - the main focus is still on angels in the late game. But with Order, there's no other way - you either build Titans or four-legged monsters?
